Approximately 26 million Americans have high-frequency hearing loss as a result of exposure to loud noises at work or during leisure activities, such as listening to loud music. According to the Hearing Health Foundation, approximately 26 million Americans have high-frequency hearing loss as a result of exposure to loud noises at work or during leisure activities, such as listening to loud music. She notes that understanding speech is dependent on fast transmission of auditory signals through the auditory nerve - the nerve that transports sound waves from the cochlea of the inner ear to the brain.
But previous research has shown that after exposure to loud sounds, transmission of these auditory signals slows down, leading to hearing loss.
Past studies have shown that loud noises can narrow the myelin coat that protects the auditory nerve. Furthermore, loud sounds have been shown to elongate myelin sheath gaps, more commonly known as nodes of Ranvier, which auditory signals jump between in order to process sound.
For their study, recently published in the journal Frontiers in Neuroanatomy, the researchers used computational modeling to simulate thinning of the myelin coat around the auditory nerve and lengthening of nodes. The team found that hearing loss as a result of exposure to loud noises is primarily caused by the thinning of the protective myelin coat surrounding the auditory nerve, while changes to the nodes only have a small effect on hearing loss. The team says their findings may help uncover prevention strategies for hearing loss and tinnitus (ringing in the ears) and could even lead to cures for the conditions.
They now plan to test drugs that trigger myelin repair to see if they can restore hearing following hearing loss. Medical News Today recently reported on a study from Brigham and Women's Hospital in Boston, MA, which suggests women who drink more coffee are less likely to develop tinnitus.

Our sense of hearing is a complex process that takes vibrations in the air and transmits them to our brain for processing.
Damage caused by loud noises is one of the chief sources of hearing loss, especially in teens and young adults.
According to the National Institute on Deafness and Other Communication Disorders, over 26 million Americans between the ages of 20 and 69 suffer from NIHL caused by work or recreational activities. It is possible for NIHL to occur from a single event like an explosion, which is why combat veterans are especially vulnerable to this type of hearing loss.
If the noise-induced hearing loss is caused by gunshots, an explosion or some other loud burst of sound, it can rupture the eardrum and damage bones in your middle ear. For more long-term noises, the excessive vibrations damage and eventually destroy small hair cells in your cochlea, which over time can cause sounds to be muffled. Like we explained earlier, noise-induced hearing loss is the only type of preventable hearing loss. Move away from any noise as soon as possible if you can’t reduce the noise or protect your ears. If you’re suffering from noise-induced hearing loss, you may be frustrated that you can’t hear phone conversations that well.

Noise is one of those health threats that many of us don't take very seriously, but we should.

According to the researchers, exposure to 100 dBA for as briefly as two minutes a day could lead to hearing loss in some regular riders. A better solution when you're encountering the subway, concerts, or any other noisy environment is to wear protective earplugs.

As fans around the country raced to make their stadium the loudest this fall, pride wasn’t the only thing hanging in the balance. On average, accounting for peaks in cheering, stadium noise blares at around the mid-90s decibel range. As research continues on noise-related hearing problems, it’s becoming increasingly clear that once you hear “ringing” (like after leaving a stadium or a concert), there’s been some damage. Besides bringing a physical risk, in some cases, extended noises can be troublesome to those who live near stadiums.
But with crowds still amping up the volume to root on their favorite teams, what’s a sports fan to do? Your childrena€™s hearing can be damaged by loud noises all too easily and the hearing loss can be permanent.
Some nerve cells in the inner ear can signal tissue damage in a way similar to pain-sensing nerve cells in the body, according to new research from Johns Hopkins. A summary of the research will be published online in the journal Proceedings of the National Academy of Sciences during the week of Nov. The new discovery came as a result of interest in why this small subset of afferent nerve cells -- nerves that take information from the inner ear to the brain -- are quite insensitive to sound. Fuchs and his team knew that these type II afferents connect to specialized sensory cells in the ear of mammals. It was known that nearby supporting cells respond to outer hair cell damage by increasing their inner calcium levels and releasing the chemical messenger ATP. Fuchs says that the ATP released by the supporting cells is probably what gets the neurons to fire, and the supporting cells might release ATP in response to ATP that leaks out of the ruptured outer hair cells.
Over evolutionary time, such a mechanism could have evolved to help mammals avoid further damage to their hearing.
The good news, Fuchs says, is that the analogies with pain elsewhere in the body provide guidance for future studies. Other authors of the report include Chang Liu and Elisabeth Glowatzki of the Johns Hopkins University School of Medicine.
This work was supported by grants from the National Institute on Deafness and Other Communication Disorders (R01 DC011741, P30 DC005211). Now, a new study by researchers from the University of Leicester in the UK sheds new light on how this happens, paving the way for new prevention and treatment strategies for hearing loss and tinnitus. Martine Hamann, a lecturer in neurosciences at the University of Leicester, notes that many individuals listen to loud music without realizing it can affect their hearing later in life. Hamann says that these findings pose a question: is reduced auditory signaling following exposure to loud sounds a result of the thinning of the myelin coat or the elongation of nodes? They then assessed how each of these changes affected auditory signaling through the auditory nerve. We can’t hear the TV or radio as good as we once could, or we start to notice that we say “what?” a lot more.
But louder noises, especially ones we experience over a long period of time, can damage sensitive parts of your inner ear crucial to hearing.
Anything under 75 decibels is considered safe, even if exposed to it for a long period of time.

You may not notice, or even ignore these signs for a long time until they become too difficult. CaptionCall is a special system that allows you to read a transcript on your conversation while on the phone.
Exposure to loud noise is thought to be a contributor to hearing loss in about half of the estimated 28 million Americans who have it.
A study in the August issue of the American Journal of Public Health finds that noise levels from New York City subways are high enough to cause hearing loss in people with regular exposure.
Cranking the volume up to high on your favorite Metallica or Twisted Sister tune can produce noise levels of 100 dBA or higher. All that noise has an effect on ears, and it might last much longer than just an ear-ringing ride home after the fourth quarter. At that level, safety guidelines recommend no more than an hour of sustained noise, but most games are about triple the length.
People of all ages can be susceptible to partial deafness — and it’s important to note that loud noises are the most common cause of hearing loss in general.
Ita€™s called Noise Induced Hearing Loss (NIHL) and it can happen slowly over time or in a split second depending on the volume of sound you or your children are exposed to. If the finding, discovered in rats, is confirmed in humans, it may lead to new insights into hyperacusis, an increased sensitivity to loud noises that can lead to severe and long-lasting ear pain.
These so-called outer hair cells amplify the sound waves that enter the inner ear, giving mammals very sensitive hearing over a wide range of frequencies.
Fuchs' team knew that type II afferent neurons can respond to ATP, so they damaged outer hair cells while monitoring type II neurons in surgically removed inner ear tissue. Such effects might depend on heightened sensitivity of the type II neurons after trauma, akin to the heightened sensitivity of pain-sensing nerves in damaged skin.
For example, a compound that suppresses pain-sensing nerve cells elsewhere, also prevented type II afferent neurons from firing in response to outer hair cell death.
This is known as noise-induced hearing loss (NIHL) and is the only preventable type of hearing loss. Sources of this damaging sound can include machines you may have worked around, yard equipment like mowers and trimmers, or from repeated exposure to loud music. If you’ve been exposed to loud noises without taking precaution, it’s never too late to start.

Now, granted, I'm not exactly an avid concertgoer--you're about as likely to find me in a mosh pit as on an alien space ship--but my ears' aversion surprised me.
And if the fan next to you is screaming, that can be a quick hit of 120 decibels or so, about the same as a roaring chainsaw. The trick is to recognise what volume of sound is unsafe and take action to prevent damage. Hypersensitivity to loud sound (hyperacusis) is a paradoxical consequence of hearing loss in many people.
Tinnitus is simply noise or ringing in the ears, and affects approximately 1 in 5 according to the Mayo Clinic. She reveals the latest trends, tips, news, websites & products for baby boomers, caregivers & older adults. Everyday noises such as slamming doors, clanking dishes and barking dogs can become irritating and even painful.
