The dos and don’ts of caring for your hearing aids

Proper care and maintenance of your hearing aids is important. It will ensure you to get the most out of your aids, prevent problems and maintain optimum hearing conditions. Here are some guidelines to help you care for them. DO: clean your hearing aids regularly with a dry cloth or tissue. DON’T: get your hearing aids wet. That means no wearing them in the shower or when swimming. If they happen to get wet, dry it off immediately. DO: put your hearing aids in their case when you’re not using them DON’T: wear your aids when using aftershave, hairspray, perfume, sunscreen, insect repellent and so on. They contain chemicals that could damage it. Allow time for drying before putting back on hearing aids. DO: use a moisture protection kit/anti-humidity kit. They help with moisture problems (which can affect performance of hearing aids) and extend life of hearing aids. DO: keep out of reach of pets and visiting grandkids. Dogs have been known to chew them up and if swallowed by either pet or grandkid, can be very dangerous. DON’T: expose your device to extreme heats. Don’t leave them in a parked car, near a heater or wear while using a hairdryer. DO: Store your hearing aid in a safe place that's dry and cool. DON’T: leave your hearing aids switched on when you’re not using them. DO: change batteries often so you won’t be stuck with aids that have suddenly run out of power. DON’T: ever insert anything into the sound outlet as it could damage the receiver. If you can’t clean it properly, ask your hearing professional. DO: remove any earwax that gets into your hearing aid. It could cause permanent damage. Image credits: Getty Images

How to fall asleep without sleeping pills: 7 natural sleep aids that actually work

It’s 3am and you’re suddenly wide awake. Try these seven science-backed strategies to fall back to sleep fast. Give meditation a try As a mindfulness coach, I’m very aware of the day-to-day anxieties and worries that can interfere with a good night’s sleep. One of the most effective natural sleep aids is a quick meditation session to ease yourself out of those stresses. If you’ve never meditated before, you’ll likely find the meditation interrupted by thoughts flashing through your mind. It’s important for you to know that this isn’t a failure on your part, and that you aren’t doing anything wrong. Thinking is just what the brain does, as naturally as lungs take in air. The point is to be non-judgmental yet aware of your thoughts, bodily experiences and breath, moment by moment. Stop wanting to fall asleep It’s counterintuitive, isn’t it? Sometimes trying too hard to do something is the very thing that prevents us from achieving it – and that’s never more true than when it comes to falling asleep. Desperately wanting to sleep will only stoke anxieties that will further stress your brain, essentially feeding it the message that it’s not safe to sleep. Throw in those worries about your to-do list at work the following day, and the whole thing can snowball into a panic attack. Try letting go of that feeling that you absolutely must sleep now, and observe your own anxieties for what they are without judgment. When you stop looking at sleep as a goal, you’ll find it easier to fall asleep. Start a journal If you find yourself struggling to fall asleep, pick up a pen and paper (not your phone!), and start writing: simply scribble down an account of what’s going on inside your head. Although there’s no “right” way to journal, you might start by listing the events of your day, and from there, how those events and encounters made you feel. Building this structured picture of your thoughts may help you see that the problem that’s keeping you up at night, and is likely less overwhelming than you thought. Why my insistence on a pen and paper? First off, studies show the simple motor action that’s involved in the act of handwriting has a calming effect. Secondly, the light emitted by laptops and phones isn’t conducive to falling asleep. Find yourself a "3am friend" Some of us are lucky to have a ‘3am friend’, that close confidant you can call up in the wee hours knowing that they won’t hold it against you in the morning. Although it’s great to have someone to talk to when you want to fall asleep, it’s important that the conversation doesn’t just rehash the anxieties that are preventing you from catching shut-eye in the first place. Rather than using the call to seek solutions for those issues, talk about things that calm your nerves, or even have them assist you in deep breathing. It may sound silly, but doing a series of deep, relaxing breaths can help you let go of the troubles that are keeping you wide awake. Take a warm shower Taking a warm shower not only relaxes your muscles and soothes minor aches and pains, but it also raises your core body temperature. As soon as you step out of the shower, your body starts working at lowering that temperature, which is something that normally happens when you’re falling asleep naturally. (That’s why we always feel the need for a blanket when we sleep, no matter how warm it is!) By kick-starting that temperature-lowering process, you’re tricking your body into falling asleep fast. Stretch yourself to sleep Anxiety keeping you up? Research suggests mild stretching can help take the edge off and relax muscles that have become stiff and sore after a long day. We’re not talking intricate yoga poses or acrobatics here, either: Simple stretches like an overhead arm stretch and bending over to touch your toes should do the trick. Ramp up the relaxation potential with a soundtrack of ambient noise at a volume that’s just barely audible. There are plenty of white noise apps that are free to download, but soft music can work as well (so long as there are no lyrics). Just remember, if you’re using an electronic device to play these sleep-promoting sounds, make sure it’s placed screen-down so you’re not distracted by the light it emits. Read (or listen!) to something new When you’re struggling with insomnia, it might be tempting to pull an old favourite off the bookshelf. In reality, it’s better to read or listen to an audio book that covers a topic on which you know absolutely nothing. New information, while taking attention away from the stressors that are keeping you up at night, gives your brain enough of a workout to make it tire more quickly than when it’s engaged with familiar subjects and concepts. Again, if it’s an audio book or podcast you’re listening to, make sure the light-emitting side of the device is face down to keep the room as dark as possible. Darkness and warmth play an essential part in the production and maintenance of melatonin, the hormone that plays the central role falling asleep.

Paul Simon reveals sad health update

At 82 years of age, the great Paul Simon – one half of the iconic duo Simon & Garfunkel – has admitted to facing a new health challenge that could prove devastating to millions of fans worldwide: hearing loss. In a recent revelation, he spoke candidly about how this health issue has affected his performances, yet also how he's adapted in oder to continue pursuing his passion for music. Simon's discussion about his hearing loss comes ahead of the premiere of a two-part docuseries, In Restless Dreams: The Music of Paul Simon, set to air on MGM+ starting March 17. It's a timely revelation, shedding light on the personal struggles behind the legendary musician's enduring career. During a panel discussion, Simon disclosed the impact of his hearing loss on his recent stage experiences. While he's regained some comfort in singing and playing instruments, he noted difficulties when certain instruments overshadow his own voice. "If there's a drum or an electric guitar," he revealed, "it's too loud and I can't hear my voice. But when I first lost the hearing, I couldn't get – it threw me off." It's a frustration that resonates deeply with any performer reliant on auditory cues for their craft. Simon's journey with hearing loss began suddenly, with the loss predominantly affecting his left ear. In a previous interview, he described the initial frustration and annoyance at the unexplained condition, hoping it would eventually resolve itself. "Nobody has an explanation, so everything became more difficult," he said in a Times interview in May 2023. "My reaction to that was frustration and annoyance; not quite anger yet, because I thought it would pass, it would repair itself." Despite the challenges, he's found solace and creative expression through his daily guitar playing, using it as both a creative outlet and a source of comfort during trying times. Reflecting on his musical journey alongside Art Garfunkel, Simon highlighted the enduring impact of their collaboration. From their humble beginnings as schoolmates in New York to becoming one of the best-selling music acts of the 1960s and 1970s, Simon & Garfunkel's legacy is undeniable. Their timeless hits, including "The Sound of Silence," "Mrs Robinson," and "Bridge Over Troubled Water," continue to resonate with audiences worldwide. Despite occasional tensions and artistic differences that led to their split in 1970, Simon & Garfunkel's partnership endured, marked by intermittent reunions for select performances. Their ability to transcend personal conflicts in the pursuit of their shared musical vision speaks volumes about their dedication to their craft and the enduring power of their bond. While Simon's journey may have taken an unexpected turn, his musical legacy continues to shine brightly, resonating with generations past, present and future. Images: Getty

"Do you hear it?": Worldwide hum global mystery baffles scientists

A perplexing phenomenon known as "The Worldwide Hum" has been capturing the attention of scientists and citizens alike, as an unusual low-frequency noise continues to puzzle experts. This mysterious hum, first recorded in 2012, has been reported by thousands of people worldwide, sparking investigations, online discussions and even <a href="https://www.thehum.info/" target="_blank" rel="noopener">the creation of an interactive map</a> documenting instances of the enigmatic sound. As researchers strive to unravel the mystery, individuals share their experiences, raising questions about its origin and effects. Described as a low rumbling or droning sound, "the hum" is often likened to the idling of a car or truck engine. What makes this phenomenon particularly intriguing is that it is not universally heard, with reports of the hum being exclusive to certain individuals. Some claim it is more pronounced at night than during the day, and louder indoors than outdoors. One Reddit user even compared it to the low-frequency vibrations felt when a passenger jet flies overhead. Since its first documentation, more than 6,500 instances of the hum have been reported globally, with new cases continually emerging. The interactive user-generated World Hum Map and Database Project captures the experiences of those who have encountered the sound, providing a comprehensive overview of its widespread occurrence. In some regions, authorities such as the Environment Protection Authority (EPA) have conducted investigations, as was the case in the NSW Waverley Council ten years ago. Despite these efforts, the source of the hum remains elusive. Individuals affected by the mysterious noise often find solace in online communities, where they share their experiences and discuss possible explanations. Some describe feeling as though they are "going insane", and say that the psychological impact of the persistent hum is actually very severe. Facebook support groups have become a platform for individuals to connect, share anecdotes and speculate about the origin of the sound. Theories range from the mundane – such as the use of headphones causing collective tinnitus – to more complex environmental factors. While tinnitus, a symptom of auditory system issues, has been proposed as a potential explanation, it does not account for the collective experience of the hum. Various theories, including industrial plants, ocean waves, lightning strikes and the proliferation of mobile phone towers, have been suggested over the years. However, none of these explanations have gained widespread acceptance or provided a conclusive answer. Dr Glen MacPherson, who initiated the World Hum Map and Database Project, experienced the hum firsthand on Canada's Sunshine Coast. Having debunked the idea of "hum hotspots", Dr MacPherson theorises that the hum may be a subjective phenomenon, akin to tinnitus, originating from within the individual rather than an external source. His 11 years of research highlight the complexity of the mystery, challenging initial assumptions and pointing towards the need for further investigation. As "The Worldwide Hum" continues to captivate the curiosity of scientists and citizens worldwide, the quest for understanding remains elusive. While theories abound, the true origin of the hum remains unknown, leaving both experts and individuals alike intrigued by a phenomenon that transcends geographic boundaries and defies conventional explanations.

The path to better hearing, today

In 1902, Princess Alexandra of Denmark, who would very soon become Queen Consort of the United Kingdom alongside King Edward VII, found herself enraptured by a fascinating new device that was fast becoming the talk of Europe. The young princess had been fitted with one of the world’s first portable electric hearing aids, and it proved to be a life-changing success. Back in Denmark, the impact of this event became a clarion call to one Hans Demant, a bicycle manufacturer and purveyor of sewing machines. His wife, Camilla, also suffered from severe hearing loss and so, after a determined journey to London, Hans returned with a precious electric “Acousticon”. Witnessing Camilla’s progress served as a source of inspiration for Hans to extend his assistance to a broader community of individuals suffering with hearing loss, and so he initiated the import of hearing devices from America. In 1904, Hans Demant founded the company that would later become known as <a href="https://www.oticon.co.nz/">Oticon</a>, a name now synonymous with cutting-edge hearing solutions, paving the way for the modern hearing aids we know today and bringing new-found joy to millions worldwide. <h3>Hearing health</h3> Hearing health is a such critical aspect of our overall well-being, yet it often goes overlooked until problems arise. In New Zealand, hearing issues affect a surprisingly large portion of the population, with a 2022 EHIMA report estimating as many as one in ten New Zealanders are living with hearing loss. Sadly, a lack of awareness can lead to irregular hear- ing check-ups, which in turn leads to delayed diagnosis and treatment. <h3><img class="alignnone size-full wp-image-50616" src="https://oversixtydev.blob.core.windows.net/media/2023/11/miniRITE_R_H1-2023_RightLeft_C090ChromaBeige_LEDgreen_Speaker60_OpenBassDome_500pctSize_w_shadow_1280.jpg" alt="" width="1280" height="642" /></h3> <h3>A new world of sounds</h3> A far cry from the bulky hearing aids of over a century ago that were hailed as a miracle in the press and transformed Queen Alexandra’s life, the pinnacle of today’s devices – such as <a href="https://www.oticon.co.nz/hearing-aid-users/hearing-aids/products/real" target="_blank" rel="noopener">Oticon Real™ hearing aids</a> – continue to change the way we experience the world of sound.

"Death was a blessing": Why father was glad to hear his daughter was killed

A devastated, recently widowed father has revealed why he was relieved his eight-year-old daughter was killed by Hamas terrorists in Israel. Thomas Hand, an Irish-born father who moved to Israel 30 years ago, tearfully told CNN that he welcomed the news that his daughter, Emily, had been killed quickly by Hamas, because it was better than being taken hostage and tortured by the terrorists. Mr Hand was already grieving the loss of his wife, who died of cancer in recent years, when his daughter was killed during the conflict between Israel and Palestine. In the heartbreaking interview, Mr Hand broke down in tears as he recounted the moment he was finally told his daughter's body had been found, and said his reaction was one of relief that she had not been kidnapped instead. He said in a shaking voice, "They just said we found Emily, she's dead and I went, 'yes'. I went, 'yes' and smiled because that is the best news of the possibilities that I knew." <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/CySvzswoJFb/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/CySvzswoJFb/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by CNN (@cnn)</a> </div> </blockquote> "That was the best, possibly that I was hoping for.

Revealing harrowing details of events surrounding the attack, he shared why he survived and his daughter did not. "She doesn't do it very often, but unfortunately that night, that particular night - Friday night - she went to sleep at her friend's house."

6 natural remedies for tinnitus

As anyone who’s ever experienced will agree, tinnitus is about as fun as repeatedly stubbing your big toe. But the good news is needn’t suffer in silence. There is a range of natural remedies available, and while these won’t eliminate tinnitus completely they may be used to help manage the condition. Before we go through some of the natural remedies, it might be useful to take a moment to understand what tinnitus actually is. Tinnitus is a physical condition that is usually caused by a fault in the hearing system where someone experiences noises or ringing in their ears when there is no external noise presents. It’s important to know tinnitus is symptom, and not a disease. It can be caused by a variety of things including exposure to loud noises, earwax blockages, ear-bone changes and age-related hearing lost. 1. Gingko biloba Across the board, gingko biloba is generally considered one of the stronger herbal remedies for tinnitus. This widely available herbal remedy is often used to improve blood circulation, which can reduce the ringing sensation and improve the function of your ears. It also contains handy antibacterial and antifungal properties that can help eliminate any existing infections. 2. Apple cider vinegar Apple cider vinegar provides a particularly useful daily tonic to help reduce the effects of tinnitus. A natural antifungal and anti-inflammatory agent, apple cider vinegar also works to alkalize your body and help rebalance your internal levels. Again, this remedy is quite helpful when it comes to getting rid of any underlying infections or fungus that may be contributing to your tinnitus. 3. Alpha lipoic acid Alpha lipoic acid provides tinnitus sufferers with another handy supplement that can help minimise the effects of this condition. Functioning as an antioxidant, this vitamin-like chemical is known to help treat cell damage and restore natural vitamin levels in your body. Alpha lipoic acid has also been known to help improve neuron function and conduction, which may be contributing factors. 4. Holy basil Here’s another natural remedy for treating tinnitus. Holy basil is known to contain a range of antibacterial properties and can be used to help kill the bacteria that may be contributing to the problem. In addition, holy basil can also be used as a way to provide you with relief from more severe forms of ear pain. It won’t solve the problem, but it will make it easier to manage. 5. Onions and garlic While they might not make your breath smell the best on a hot date, onions and garlic have been used in the past to provide relief for tinnitus sufferers. Onions contain medicinal and antibacterial properties to help fight infections, while garlic can help reduce inflammation and improve blood circulation, which is particularly useful for tinnitus that is caused by high altitudes. 6. Saline solution Here’s another nifty way to treat tinnitus naturally. Saline solution can help clear any blocked nasal passages and ease the pressure caused by excessive fluids that are building up in your sinuses. This simple remedy is a great way to provide effective relief from particular forms of tinnitus. So there you go, six handy ways to help relive yourself of the effects of tinnitus. Ultimately we would recommend that you go to a doctor and get a proper diagnosis if you happen to be suffering from tinnitus, but at the very least it’s handy to know that these natural remedies are around.

These 11 simple everyday things could be ruining your hearing

Protect your ears You know a leaf blower can do a number on your hearing or a loud rock concert can make your ears ring for days. But there are all sorts of surprising everyday items that can have an impact on your hearing, and you don’t want to wait until you’re collecting Social Security to take action – Millennials are losing their hearing, too. From your kitchen to your yard, your medicines to your health conditions, here are things that affect your ears. Take a listen. Blood-related conditions Types 1 and 2 diabetes, high blood pressure and high cholesterol affect almost every cell in the body – including the ears. Vibrations from tiny hair cells in your ears send your brain messages about what you’re hearing, but those cells need proper blood flow. “All those hair cells are fed nutrients by tiny little capillaries,” says audiologist Craig A. Kasper. “If there’s any problem with blood flow, you’re not going to get those hair cells to grow.” People who have diabetes, for instance, are twice as likely to experience hearing loss than the rest of the population, he says. Blow-dryers A hairdryer near your head could be putting out 85 or more decibels of noise. Long or repeated exposure to sounds at or above 85 dB is when people are at risk of hearing loss, says the US National Institutes of Health. You’d probably have to dry your hair for eight hours straight before it did any damage, but that loud part of your beauty regime could add up over time, says clinical audiologist Kit Frank. “The more you use [blow-dryers] and the longer you use them, the more likely you are to have damage,” she says. “It might not do immediate damage, but over time it will.” Loud music You know what it was like when you came home after a loud concert: The ringing in your ears was a sure sign the music was too loud. But even the tunes coming through your headphones could damage your ears. Earbuds are typically more damaging than over-the-ear headphones because they rest deeper in your ear canal, says Frank. And if you crank up the volume to drown out the noise around you, things get even riskier, says Kasper. “You typically have to compete with the environmental noise to hear the music,” he says. “That’s when it becomes dangerous.” Sticking with volume at or below 60 per cent will keep the sound at a safe level, he says. If you can’t hear at that volume, buy sound-blocking headphones to cut out the outside noise. Skipping your annual check-up Most hearing loss comes from gradual damage to your inner ear, but blockages are totally treatable. During your annual visit to your GP, your doctor should check the inside of your ears for wax build-up. Skip that check-up and you might end up with clogged earwax muffling your hearing, says Frank. But you might also get stuffed-up ears after a specific event, says Kasper. “It could be someone has a history of sinus infections or allergies, or just took multiple plane rides and their ears are clogged,” he says. “It makes us feel like we’re underwater." Prescriptions Hearing loss could be a side effect of your medication. Some diuretics for heart disease, chemotherapy and antibiotics (especially gentamicin, neomycin, and others in the -mycin family) could damage your ears. Getting better is your first priority, but it’s worth talking to your doctor about whether the dose is high enough to do damage. “High doses of any antibiotic can be dangerous,” says Frank. “Usually myacins are used in high doses.” Over-the-counter pain relievers Even pain relievers you get over the counter, like aspirin and ibuprofen, could do damage in high amounts. Any hearing loss or tinnitus from them is usually temporary, but the side effects are sometimes permanent. As long as you stick with baby aspirin or regular doses of a pain medication, though, you won’t risk ruining your hearing, says Kasper. High fever As if a high fever weren’t bad enough, that elevated temperature could also damage the nerves in your inner ear, either because of inflammation or lack of oxygen. “If you don’t get that oxygen to the nerves, they break down and they don’t work like they should,” says Frank. Exercise classes Exercise classes are often very loud. The music blasting at your group workout might power you through your sweat session, but it might be working your ears in a bad way. “If you walk out of spin classes and your ears are buzzing, that’s an indication that you may have done damage to your ears,” says Kasper. Download an app to your smartphone to measure the sound level around you throughout your day, he recommends. Consider using hearing protection if your fitness centre is particularly noisy. Kitchen appliances Noisy appliances like blenders and coffee grinders could do damage to your ears over time. The more often you get those noisy blades going, the more trauma your ears go through. Hard-core chefs should consider ear protection, though the occasional smoothie isn’t anything to worry about. “If you’re in the kitchen and cooking and using a blender all day, that’s a problem,” says Frank. “If you use it for ten seconds once a week, it probably won’t be a problem for you.” Power tools The racket from lawnmowers, jackhammers, leaf blowers, drills and other power tools isn’t just a headache, it also risks hearing damage. You’ll need to protect your ears, but earplugs might not be the best choice. Putting fingers grimy from the tools so close to your ear canal could put you at risk for infection, says Kasper. Instead, pick up a pair of earmuffs from the hardware store. “They go right over the ear, and they’re easy to take on and off,” Kasper says. Your commute Public transport can be noisy, and sitting on a train or bus for half an hour to and from work could add up over time and hurt your ears, says Frank. Plus, the siren of an emergency vehicle passing you on the street could be loud enough to do some damage. “Covering your ears is a good thing – it’s not silly,” says Frank.

Survey reveals over a third of us are neglecting our hearing

A survey conducted by hearing healthcare group Audika - and hosted by Decibel Research - has revealed the hard truth that Australians just aren’t keeping on top of their hearing. Research even found that for 88% percent of respondents - 1,020 individuals over the age of 40 - the thought of losing their eyesight was a bigger concern than losing their hearing. People had a whole host of reasons, but most circled back to the stigma that surrounds hearing loss - they feared that hearing aids would make them look older, or that they might be too uncomfortable, or even that they’re simply too expensive for the average person, despite 37% of those surveyed admitting that they would probably benefit from one. 34% - roughly one third of the participants - confessed that they probably do have difficulty hearing, but have never undergone testing or sought out any sort of treatment. Meanwhile, 61% admitted that the chances of them partaking in a hearing test in the following 12 months were slim to none. Even more concerning were the 51% - over half of those surveyed - said that they would put off wearing a hearing loss “as long as possible”, even to their own detriment. Their minds wouldn’t change even if they received a hearing loss diagnosis. And this is all despite 69% of those with hearing loss reporting that their lives had been negatively impacted, from 35% citing their personal relationships as the area of concern to 35% noting their social life in general, and 19% looking to their career. Those same respondents shared that they have experienced difficulty communicating and that others don’t always understand them, often withdrawn from various events, and have faced a lack of confidence in navigating social situations. None of which can have been helped by the jokes from loved ones that a quarter of them also reported. It is more important than ever to address these statistics, and to overcome the stigma that surrounds hearing loss, as the World Health Organisation has estimated that by 2050, 1 in every 4 people around the world will experience hearing loss of some degree. On top of this, it’s believed that up to one third of the world’s population may be both undiagnosed and consequently untreated. Luckily for us, preventative measures can be taken, and the first - and arguably most important step - is to take our hearing health seriously, and make the necessary changes that will benefit us in the long run. The importance of taking such measures cannot be stressed enough, from managing symptoms all the way to preventing other “serious health conditions”. As Audika’s Audiologist and Clinical Trainer Lauren McNee put it, “poor hearing, if untreated, is linked to a number of other health conditions including mental health challenges. “The results of the recent survey indicate that Aussies don’t seem to be aware of how common hearing loss can be. They also appear to be unaware of the serious daily impacts that are felt by people that are hard of hearing, and their loved ones. “Unfortunately, stigma surrounding hearing health is still prevalent across our society – yet more than half (51%) of the survey respondents said that they have a loved one that experiences it. “With greater understanding of the impacts of hearing loss and compassion for each other, we can work towards more open conversations around hearing loss and encourage those we care about to be more proactive with their hearing health.” To help Australians on their way towards a better hearing future, Audika are encouraging people over the age of 26 to head out, learn to ‘Love Your Ears’, and visit an Audika clinic for a free hearing check.

"I can't hear you!": New feature set to do away with subtitles

Nothing is more annoying than sitting in front of your TV, eager to watch your favourite show only for the dialogue to be completely wiped because of cars passing by or a plane taking off. Not being able to hear the dialogue in a TV show or movie, especially in an action or crime-driven blockbuster where anything exploding masks all dialogue has been an everlasting problem for viewers. Netflix has revealed that 40 per cent of subscribers have subtitles on at all times while surveys in the US and UK saw anywhere between 60 and 70 per cent of young viewers as frequent users of subtitles. If you’re using subtitles for the purpose of hearing the dialogue rather an accessibility reasons, streaming giant Amazon is introducing a new feature that could eradicate the need to turn them on because of the sound mix. The feature is called ”dialogue boost" and it raises the volume of the dialogue track relative to the score, ambient sound or effects. Although Amazon has so generously offered this solution to subscribers, the dialogue boost feature will only be available on a handful of Amazon Prime Video’s originals, like Beautiful Boy, Being The Ricardos, Jack Ryan and The Marvelous Mrs Maisel. A similar feature already appears on some expensive sound systems and TV sets, but Amazon boasts it’s the first streaming platform to roll it out worldwide. To work the feature, select it from the audio and subtitles drop-down menu on an individual title, there will be two options to select from, “English Dialogue Boost: High” or “English Dialogue Boost: Medium”. The title page for a TV series or movie will show whether the dialogue boost is available. According to Variety, the helpful feature was originally designed for hearing-impaired viewers. Rest assured, if you struggle to hear the dialogue due to the sound mix, there's help on the way, granted it's exclusive to Amazon. Image credit: Shutterstock

3 things to consider when travelling with hearing loss

Hearing loss is a challenge, but with some preparation your holiday can go off without a hitch. Here are five ways to manage hearing loss while travelling. 1. While you’re at the airport If you think you’re going to require assistance boarding the plane or during your flight, it’s a good idea to inform your airline at least 48 hours before boarding. It’s also a good idea to ask staff to inform you personally when the plane is ready to board, or stand near the boarding desk as it might be difficult to hear announcements over the loudspeaker. 2. While you’re on the plane Cabin crew are generally well trained to cater for travellers with hearing loss, but it’s a good idea to explain your difficulties as you’re boarding. That way they can keep you informed of any important messages on your trip regarding delays or even emergencies. Some airlines will even board you first, and provide you with an individual safety briefing. 3. When you arrive at your destination There’s a few things to consider when you reach your destination, but it’s generally a good idea to make sure you have enough batteries for your trip with a few spare ones thrown in. It’s generally a good idea to bring a decent supply (better to take too many than too few) and spread them out over too bags in case one of them is lost in transit. Also, if you’re travelling anywhere that’s humid or tropical it might also be an idea to pack a dehumidifier pack to minimise the change of corrosion of the device. Image credits: Getty Images

5 sounds you hear on the plane explained

Nervous fliers know just how freaky a sudden noise on the plane can be, but we’ve broken down the most common ones you’ll hear and what they mean so you can travel with ease. <ol> <li>The puff of air at the gate – it’s usually one of the first unsettling sounds you’ll hear on the plane, but it’s one of the most important – it signals that the ventilation on the plane has been switched on. It’s also why lights can tend to flicker, as the plane is moving from an off-board power source to an onboard system.</li> <li>The “bark” during taxi – before take-off and landing, it’s normal for the plane to make a sort of “barking” noise. This is just the hydraulics kicking in, ensuring steering, braking and air pressure are all at optimum levels for a safe departure or arrival.</li> <li>The wings “whirring” – upon take-off and even during flight, you may hear a “whir” coming from the wings. This sound indicates the wingspan is expanding and retracting to help assist take-off and speed maintenance.</li> <li>The “bang” from the belly of the plane – this noise can be pretty scary as you make your descent into your destination, but it’s completely safe. All it means is the landing gear is being released so you can arrive safely.</li> <li>The brakes “screeching” – don’t be alarmed by this sound, it’s just the plane’s natural response to landing at the speed of 160 to 240 kph while carrying hundreds of tonnes of cargo and passengers.</li> </ol> Image: Getty

How satellites, radar and drones are tracking meteorites and aiding Earth’s asteroid defence

On July 31 2013 a <a href="https://cneos.jpl.nasa.gov/fireballs/" target="_blank" rel="noopener">constellation of US defence satellites</a> saw a streak of light over South Australia as a rock from outer space burned through Earth’s atmosphere on its way to crash into the ground below. The impact created an explosion equivalent to about 220 tonnes of TNT. More than 1,500km away, in Tasmania, the bang was heard by detectors normally used to listen for <a href="https://www.dfat.gov.au/international-relations/security/asno/Pages/australian-ims-stations" target="_blank" rel="noopener">extremely low-frequency sounds</a> from illegal tests of nuclear weapons. These were two excellent indications that there should be a patch of ground covered in meteorites somewhere north of Port Augusta. But how could we track them down? My colleagues and I who work on the <a href="https://dfn.gfo.rocks/" target="_blank" rel="noopener">Desert Fireball Network (DFN)</a>, which tracks incoming asteroids and <a href="https://dfn.gfo.rocks/meteorites.html" target="_blank" rel="noopener">the resulting meteorites</a>, had a couple of ideas: weather radar and drones. Eyes in space Finding meteorites is not an easy task. There is a network of high-quality ground-based sensors called the <a href="https://gfo.rocks/" target="_blank" rel="noopener">Global Fireball Observatory</a>, but it only covers about 1% of the planet. The <a href="https://cneos.jpl.nasa.gov/fireballs/" target="_blank" rel="noopener">US satellite data</a> published by NASA covers a much larger area than ground-based detectors, but it only picks up the biggest fireballs. What’s more, they <a href="https://academic.oup.com/mnras/article/483/4/5166/5256650" target="_blank" rel="noopener">don’t always give an accurate idea of the meteor’s trajectory</a>. So, to have any chance to find a meteorite from these data, you need a little outside help. Weather radars In 2019, Australia’s Bureau of Meteorology started making its weather radar data <a href="https://www.openradar.io/" target="_blank" rel="noopener">openly available</a> to researchers and the public. I saw this as an opportunity to complete the puzzle. I combed through the record of events from the Desert Fireball Network and NASA, and cross-matched them with nearby weather radars. Then I looked for unusual radar signatures that could indicate the presence of falling meteorites. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=334&fit=crop&dpr=1 600w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=334&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=334&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=420&fit=crop&dpr=1 754w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=420&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/496384/original/file-20221121-22-iwtkve.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=420&fit=crop&dpr=3 2262w" alt="An annoyed aerial photo showing the locations of the Woomera radar station and the falling meteorites." /></a><figcaption>The Woomera weather radar station captured reflections from the falling meteorites. Curtin University, Author provided</figcaption></figure> And bingo, the 2013 event was not too far from the Woomera radar station. The weather was clear, and the radar record showed some small reflections at about the right place and time. Next, I had to use the weather data to figure out how the wind would have pushed the meteorites around on their way down to Earth. If I got the calculations right, I would have a treasure map showing the location of a rich haul of meteorites. If I got them wrong, I would end up sending my team to wander around in the desert for two weeks for nothing. The search I gave what I hoped was an accurate treasure map to my colleague Andy Tomkins from Monash University. In September this year, he happened to be driving past the site on his way back from an expedition in the Nullarbor. Thankfully, Andy found the first meteorite within 10 minutes of looking. In the following two hours, his team found nine more. <figure class="align-center "><img src="https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/496385/original/file-20221121-16-he3p7h.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Photo of several people walking through a desert field looking at the ground." /><figcaption>A field team from Monash University searched for meteorites in the strewn field.

This first search confirmed there were lots of meteorites on the ground. But how were we going to find them all? That’s where the drones come in. We used a method developed by my colleague Seamus Anderson to <a href="https://gfo.rocks/blog/2022/03/14/First_Meteorite_Found_with_Drone.html" target="_blank" rel="noopener">automatically detect meteorites from drone images</a>.

Curtin Uni, Author provided</figcaption></figure> Strewn fields <a href="https://onlinelibrary.wiley.com/doi/10.1111/maps.13892" target="_blank" rel="noopener">tell us a lot</a> about how an asteroid fragments in our atmosphere. That’s quite important to know, because the energy of these things is comparable to that of nuclear weapons. For example, the 17-metre asteroid that exploded over Chelyabinsk in Russia in 2013 produced an explosion 30 times the size of the bomb dropped on Hiroshima in 1945. So when the next big one is about to hit, it may be useful to predict how it will deposit its energy in our atmosphere. With new telescopes and better technology, we are starting to see some asteroids <a href="https://skymapper.anu.edu.au/news/great-balls-fire/" target="_blank" rel="noopener">before they hit Earth</a>. We will see even more when projects such as the <a href="https://www.lsst.org" target="_blank" rel="noopener">Vera Rubin Observatory</a> and the <a href="https://atlas.fallingstar.com" target="_blank" rel="noopener">Asteroid Terrestrial-impact Last Alert System (ATLAS)</a> are up and running. These systems might give us as much as a few days’ notice that an asteroid is heading for Earth. This would be too late to make any effort to deflect it – but plenty of time for preparation and damage control on the ground. The value of open data This find was only made possible by the free availability of crucial data – and the people who made it available. The US satellites that detected the fireball are presumably there to detect missile and rocket launches. However, somebody (I don’t know who) must have figured out how to publish some of the satellite data without giving away too much about their capabilities, and then lobbied hard to get the data released. Likewise, the find would not have happened without the work of Joshua Soderholm at Australia’s Bureau of Meteorology, who worked to make low-level weather radar data openly accessible for other uses. Soderholm went to the trouble to make the radar data <a href="https://www.go-fair.org/fair-principles/" target="_blank" rel="noopener">readily available and easy to use</a>, which goes well beyond the vague formulations you can read at the bottom of scientific papers like “data available upon reasonable request”. There is no shortage of fireballs to track down. Right now, we’re on the hunt for a meteorite that was spotted in space last weekend before <a href="https://www.nytimes.com/2022/11/19/science/fireball-asteroid-toronto-new-york.html" target="_blank" rel="noopener">blazing through the sky over Ontario, Canada</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/194997/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> Writen by Hadrien Devillepoix.

5 interesting facts about how we hear

The cochlea is the most complex part of the ear, responsible for turning sounds waves into what we perceive as “hearing”. Here are five more facts about this amazing organ. 1. The cochlea turns sounds into “hearing” The cochlea receives sounds in the form of vibrations and converts them into nerve impulses. These impulses are sent to the brain to be translated into sounds that we recognise and understand. 2. The cochlea is the size of a pea Located in the inner ear, the cochlea looks like a snail shell (cochlea is Greek for snail) and is only the size of a pea. Yet within the small pea is everything needed to turn sound vibrations into hearing. 3. There are over 20,000 nerve cells in the cochlea There are approximately 24,000 hair fibres in the cochlea, which are essential to hearing. If these hair cells become damaged, hearing impairment occurs. 4. Cochlear implants directly stimulate auditory nerve A cochlear implant bypasses damaged hair cells in the cochlear to provide direct stimulation to the auditory nerve. 5. The cochlea can’t heal The cochlea cannot heal so damage done to your ear when younger can affect you later in life. It can be damaged by immune reactions, disease, drugs, chemicals, toxins, loud sounds, physical impact and ageing. Image credits: Getty Images

Pumping loud music is putting more than 1 billion young people at risk of hearing loss

Music is an integral part of human life. It’s all around us, just like sunshine, lifting our mood. We enjoy it so much that many of us take it with us everywhere on our phones or we spend weekends hitting the club scene, live-music venues or concerts. Meanwhile, many of us may have felt annoyed by loud sound from music venues or remarked on sound emanating from someone else’s headphones. We’re probably aware we should prevent hearing loss from loud industrial noise at work or from using power tools at home. A systematic review released today in <a href="https://globalhealth.bmj.com/lookup/doi/10.1136/bmjgh-2022-010501">BMJ Global Health</a> reports unsafe listening practices in adolescents and young adults from using personal listening devices (such as phones or digital music players) and going to loud clubs and gigs are common, and could be a major factor contributing to hearing loss. In fact, the authors estimate the pumping tunes could be placing up to 1.35 billion young people at risk of hearing loss worldwide. <h2>What the study looked at</h2> Systematic analysis involves looking across multiple studies to identify consistent findings. In this study, the authors included 33 peer-reviewed studies published between 2000 and 2021, involving over 19,000 people, aged 12–34. In the study, unsafe listening was identified as listening at levels above 80 decibels for over 40 hours per week. For context, this is the level above which most Australian states <a href="https://www.safeworkaustralia.gov.au/safety-topic/hazards/noise/overview#:%7E:text=Workers%20must%20not%20be%20exposed,on%20decibels%20and%20time%20exposed.">require industry</a> to implement noise protection processes such as use of hearing protectors. The study confirms the rate of unsafe listening practices is high in adolescents and young adults: 23.81% of them were listening to music on personal devices at unsafe levels and 48.2% at loud entertainment venues (though this rate is less certain). Based on global estimates of population, this translates to up to 1.35 billion young people at risk of hearing loss globally. The World Health Organization <a href="https://www.who.int/health-topics/hearing-loss#tab=tab_1">estimates</a> over 430 million people worldwide already have a disabling hearing loss and prevalence could double if hearing loss prevention is not prioritised. The results tally with our previous studies conducted by Australia’s National Acoustic Laboratories and HEARing Cooperative Research Centre. More than a decade ago we <a href="https://acc.hearingservices.gov.au/wps/wcm/connect/hso/f1f6299d-96f3-408e-be4b-0775af6d7f41/Lifetime_profile_exposure_sound_what_safe_HLPP2.pdf?MOD=AJPERES">reported</a> a high potential for hearing loss from attendance at nightclubs, pubs and live concerts in young Australians aged between 18–35 years. Back then, we found 13% of young Australians (aged 18–35) were getting a yearly noise dose from nightclubs, concerts and sporting activities that exceeded the maximum acceptable dose in industry. In 2015, the WHO launched the <a href="https://www.who.int/activities/making-listening-safe">Make listening Safe</a>initiative to encourage young people to protect their hearing. <h2>Why it’s bad for your hearing</h2> So what’s the problem with loud music? Like sunshine, overexposure can lead to harm. Loud noise, including music, can <a href="https://www.cdc.gov/nceh/hearing_loss/how_does_loud_noise_cause_hearing_loss.html">kill off hair cells and membranes</a> in the inner ear (the cochlea). Once hearing is lost, a person mightn’t be able to hear or understand speech or sounds around them. <a href="https://www.nidcd.nih.gov/health/noise-induced-hearing-loss">Research</a> shows hearing loss results from a combination of sound being too loud (and it doesn’t need to be painful to cause hearing damage), listening to loud sound too long (and the louder the sound, the less time you can listen before your hearing is at risk) and how often you are exposed (and hearing damage is cumulative over time). A good “rule of ear” is that if you hear ringing in your ears at or after listening, you are at risk of damaging your hearing. This type of hearing loss is <a href="https://www.cdc.gov/nceh/hearing_loss/how_does_loud_noise_cause_hearing_loss.html">permanent</a> and may require use of hearing aids or cochlear implants. <h2>Wait, so no loud music at all?</h2> So what can we do, short of throwing away our headphones and avoiding clubbing and live music? First, just like with the sun and skin, we need to be aware of the risks to our hearing and take the necessary steps to protect ourselves. We need to be aware of how loud sound is around us and how to keep our exposure within safe levels. We can do this by using personal hearing protection in clubs (such as <a href="https://www.nytimes.com/wirecutter/reviews/best-earplugs-for-concerts/">ear muffs or ear plugs</a> that are fit for purpose), or limiting how often we visit noisy music venues or how long we stay at really loud ones. In Australia, people can access a free <a href="https://knowyournoise.nal.gov.au/">noise risk calculator</a> to calculate their personal risk using an online sound level meter, and to explore how changes in lifestyle could protect their hearing while still allowing them to enjoy music. Most phones now come with software that can <a href="https://www.headphonesty.com/2022/03/iphone-headphone-safety/#:%7E:text=Key%20features%20of%20the%20iPhone%20Headphone%20Safety%20feature&text=According%20to%20the%20WHO%20standard,risk%20of%20sustaining%20hearing%20damage.">monitor safe listening levels</a> and limit exposure. Hearing protection at the venue level is more challenging and may require regulatory and industry-based approaches. Our <a href="https://academic.oup.com/annweh/article/64/4/342/5811673">2020 research</a> identified hazard controls for entertainment venues, such alternating volume between louder and softer levels, rotating staff, providing quiet rooms, and raising speaker locations above head height. We also showed DJs and venues were open to initiatives aimed at reducing the risk of hearing loss for their patrons and <a href="https://www.tandfonline.com/doi/abs/10.1080/19338244.2020.1828241?journalCode=vaeh20">staff</a>. Compromises are possible and they could enable enjoyment of music at live-music venues, while still protecting hearing. That way everyone will be able keep enjoying music for longer.

Music

Drop that bass (below the level of human hearing) to get bodies on the dance floor moving

People dance nearly 12% more when music includes very low frequency bass but researchers have found that it may be the sounds we don’t hear that gets our toes tapping. This is interesting news for those who’ve had an experience at a party, celebration or club when the music’s groove just isn’t making your body move and who might be tempted to reach for the nearest beverage to lubricate our joints. But maybe there’s a solution which is more subtle – and less liable to cause headaches the next day… It seems, as Meghan Trainor correctly observed in 2014, that it really is “All About That Bass.” Now, it is no revelation that bass-driven music is good for a boogie. Trainor certainly wasn’t the first to discover this critical component of the rhythm section. Researchers from Canada and Germany turned a live electronic music concert into a lab study, to find out how different qualities of music influence the body. Their results are <a href="https://doi.org/10.1016/j.cub.2022.09.035%20" target="_blank" rel="noreferrer noopener">published</a> in Current Biology. The researchers introduced over speakers levels of bass below human hearing levels. This super low pitch infrasound is made up of wavelengths of sound too long for our ears to pick up. Infrasound is common in whale song and other parts of the animal and natural world. Monitoring the crowd’s movements, the scientists found that people danced 11.8% more when the very low frequency bass was present. “I’m trained as a drummer, and most of my research career has been focused on the rhythmic aspects of music and how they make us move,” says first author Daniel Cameron, a neuroscientist from Canada’s McMaster University. “Music is a biological curiosity – it doesn’t reproduce us, it doesn’t feed us, and it doesn’t shelter us, so why do humans like it and why do they like to move to it?” Cameron and colleagues treated participants in the study to a 45-minute live set by electronic musical duo Orphx at LIVELab, a research theatre at the University. Donning motion-sensing headbands, the concert-goers’ dance moves were monitored. They were also asked to fill out survey forms before and after to ensure they didn’t detect the infrasound, to measure their enjoyment, and examine how the music felt physically. Turning the ultra-low bass playing speakers on and off every two minutes, the researchers found movement increased by 12% when the speakers were on. Vibrations experienced through touch and interactions between the inner ear and brain are closely linked to the motor system. The researchers theorise that there is a neurological link between these physiological processes and music. They believe that our anatomy can pick up on low frequencies, affecting our perception of “groove”, spontaneous movement and rhythm. Cameron suggests that the super-low frequencies may influence the vestibular system which controls body position and movement through the inner ear. “Very low frequencies may also affect vestibular sensitivity, adding to people’s experience of movement. Nailing down the brain mechanisms involved will require looking the effects of low frequencies on the vestibular, tactile, and auditory pathways,” says Cameron.

Is your dizziness caused by ear problems?

There are many causes to dizziness such as low blood pressure or dehydration, but did you know ear problems are also one of them? This occurs because the balance organ is actually located in part of the inner ear, although our sense of balance actually comes from the coordination of the balance organ, the visual system and the muscles in the body. If you’ve experienced a spinning sensation coupled with decreased hearing or ringing in the ears, your dizziness might be caused by an ear disorder. You should see your doctor for diagnosis and treatment. The most common ear-related causes of dizziness include: <ul> <li>Benign paroxysmal positional vertigo – This is a common inner-ear disorder among older people, where crystals normally located in the inner ear become dislodged. As your head moves, the crystals move causing dizziness.</li> <li>Labyrinthitis – An ear disorder that involves inflammation of the middle ear. It generally occurs after a viral infection.</li> <li>Meniere's disease – This is an inner ear disorder that causes severe hearing loss, tinnitus and dizziness.</li> <li>Acoustic neuroma – It is a non-cancerous tumour of the ear that causes ringing in the ears, hearing loss and balance problems.</li> </ul> Image: Getty

What to do if your hearing aids get wet

Like most electronic devices hearing aids should be kept clear of water but if you do happen to forget to take them off before showering or jumping in the pool, here’s what you should do if your aids get wet. The first step is to switch off your hearing aids and remove the battery. Keeping a wet battery inside your aid can further damage the device so it’s best to throw out waterlogged batteries. However, if that’s not an option carefully dry the battery with a cloth. For the hearing aids, here are some home methods to drying them: <ul> <li>Shake the hearing aids with the battery compartment open to remove any excess water. Leave aids on newspaper to air dry indoors for at least a day.</li> <li>Place wet hearing aids near a lamp can speed up drying process, but do not place too close to light bulb as too much heat can damaged the device.</li> <li>Stick hearing aids into a container of uncooked rice or silica gel. Seal container and leave overnight. Both rice and silica gel can work as a dehumidifier and soak up water.</li> <li>Use a fan or hairdryer on the lowest setting. Only use hairdryer if it has a “cool” setting.</li> <li>Do not ever use high heat to dry the aids like an oven or microwave.</li> </ul> If the above suggestions do not work, contact your hearing aid provider. Your hearing aids aren’t necessarily damaged beyond repair and your hearing aid provider can talk to you about options. Image: Getty Images

Say what? Here’s why you should check your hearing this September

With Women’s Health Week held every September, it offers us a chance to really focus on the different aspects of our health that we might not think about in our day-to-day lives. For Lauren McNee, a clinical trainer and audiologist at Audika, this week provides the opportunity to check in with something many of us ignore: hearing loss. “Overall, Australians are not taking action to look after their hearing, with only one in five planning a hearing test in the next 12 months - compared to 39 percent who intend to get an eye test in the same period,” she tells OverSixty. Over 1.5 billion people live with some form of hearing loss, ranging from mild to profound loss that can affect one or both of your ears. Though we might not think about it all that much, we rely on our ability to hear to interact with the world around us, with the <a href="https://www.who.int/health-topics/hearing-loss#tab=tab_1" target="_blank" rel="noopener">World Health Organisation</a> reporting that hearing loss can result in social isolation, loneliness and frustration, as well as $US 980 billion cost to the global economy each year. McNee says that taking the chance to check up on our ear health is particularly important as we age too, and should be among the various tests and check-ups we do to monitor our health. As we age, most of us will lose our hearing in some way, in a condition called presbycusis. According to the <a href="https://www.nidcd.nih.gov/health/age-related-hearing-loss" target="_blank" rel="noopener">National Institue on Deafness and Other Communication Disorders</a>, most of us will experience a combination of noise-induced hearing loss - from listening to sounds that are too loud or last too long - as well as age-related hearing loss which can occur because of changes to our inner ear. For women, McNee says that those with hearing loss are <a href="http://archotol.jamanetwork.com/article.aspx?articleid=1835392">more likely to suffer from depression</a> - but there are some key signs to look out for to catch hearing loss early. “Some key signs to look for include difficulty following conversations, phone conversations may be unclear, people seem to be mumbling, difficulty locating where sounds are coming from, ringing or buzzing in the ears, or even finding that you have to keep turning up the volume on the TV or radio,” she explains. “When a person’s communication becomes limited due to hearing loss, this can result in withdrawal from social activities and can lead to isolation – which we know can be a gateway to experiencing symptoms of depression.” Who’s at risk of hearing loss? Though McNee says hearing loss “doesn’t discriminate”, there are some factors that can increase your risk of losing your hearing. “It depends on a few factors, including your age and risk factors such as family history, occupation, and any pre-existing conditions like diabetes – which is known to be linked to hearing loss,” McNee explains. Whether our hearing loss is due to exposure or age, the damage and changes in our ears can’t be reversed. But, there are ways to protect your ears from other causes of hearing loss and reduce your risk of further loss. “If you are exposed to loud noises regularly, like renovations, loud music or engines, make sure you are taking steps to protect your ears at those times by wearing appropriate hearing protection,” McNee suggests. “If you like to listen to music, especially with ear bud headphones, make sure the volume is such that you can still hear others around you or keep listening time down.” McNee also suggests checking your hearing regularly, and that an annual check-up if you’re over the age 50 is best. “We usually recommend that people that aren’t exhibiting hearing loss, but are over the age of 50, get screened once a year just to be safe,” McNee says. “If you are at high-risk of hearing loss, or you are exhibiting symptoms, it’s important to get tested as soon as possible. Early detection can help reduce the risk of other related conditions such as depression.” Luckily, checking your hearing is a pretty quick and simple process, with tests offered in-person and online for free.
