Hearing loss affects 1 in 5 Americans, study finds

If you think hearing loss is just an inevitable part of aging, think again.

More than 48 million Americans over age 12 have trouble hearing in one or both ears, according to a new study published in the Archives of Internal Medicine. And the way we listen to music is partly to blame.

“Aging and genetics do sometimes play a role, but what we know now is that environmental exposures - like listening to music too loudly - can contribute to long term hearing damage over time,” says Dr. Frank R. Lin, lead study author and assistant professor of otolaryngology-head  and neck surgery and epidemiology at Johns Hopkins School of Medicine. “It’s a growing concern.”

Here’s how hearing loss happens with headphones: You have your headphones on and are jamming to your favorite tune on maximum volume. The sound waves enter the ear, travel thru the ear canal all the way to the hair cells located in your inner ear. Hair cells help convert sound energy into electrical signals sent to the brain. This,  in return, allows you to hear the music clearly. But when the volume is too loud, those hair cells get damaged and never grow back.

“The tricky thing about loud noise exposure is that most people won’t see the impact for many years later,” says Lin.  “So consumers aren’t aware they are damaging their hearing until it’s too late.”

Hearing loss is gradual. And people's susceptibility to permanent hearing loss depends on several factors including their own genetics, the background noise they are exposed to and how loud they are listening to music, according to Lin.

So how loud is too loud?

Experts don’t yet have an exact calculation as to  how loud, for how long, is too much.  But researchers do know that the louder the noise, the less time it takes to cause damage to your hearing.

Remember this number: 115 decibels (dB). That’s how loud the average MP3 player is playing music at maximum volume. According to the American Academy of Otolaryngology, listening to an MP3 player at 100db for just 15 minutes can cause hearing loss. Also, music at 85dB for prolonged, repeated times can cause damage.

“What’s important to remember is that once the hair cells in your ear have been damaged, your body can’t replace them. It’s permanent hearing damage,” says Lin, whose research is the first comprehensive national estimate of hearing loss in the United States.

So for those who want to try to keep from joining the one in five Americans with hearing loss, turn the volume down a notch and choose headphones that rest on the ear, versus ear buds that sit in the entrance of the ear canal.  And a good rule of thumb for parents: If you can hear your kid's music through their headphones, it’s probably too loud.

    Here I was hoping that we'd get an article about hearing conditions that most people are unaware of, but instead, it's just a reminder for people to turn down their music. Sad.

    I never liked loud music. In fact, I tend to strongly dislike loud sounds. Sudden, loud sounds (especially high-pitched ones) actually hurt my ears. For a few years now, however, I noticed episodes of hearing trouble. I also had vertigo episodes, and tinnitus that would come and go. It's all been getting progressively worse, and after three years of reporting these symptoms to doctors, I finally got one guy to put it together and say, "Oh! This is Meniere's disease!"

    And now, I hear about people who damage their hearing through their own bad decisions, and it just boils my blood. If you've got normal hearing, folks, cherish it and take care of your ears.

      I was hoping it would have a list of little known or rare hearing conditions. About six months ago I started losing the hearing in my right ear to loud and annoying pulsatile tinnitus. The doctors don't know whats causing it and it's ruining my life. I can't even hear my children when they ask me for something anymore.

      It may be only just a reminder but it's a good idea. For some unknown reason people riding public transportation with their headsets on think everyone else wants to hear the music they're listening to & likes the music. Same goes for people driving their cars.

      Definitely, I have a hearing loss and am legally blind. My hearing aids (with FM system cost upwards of $6000 and are not covered by insurance) are probably the number one most helpful and important piece of equipment I have to help me function and be independent. And insurance calls them a 'luxury item." Why aren't hearing aids considered durable medical equipment and why are thousands of insured people who happen to be hearing impaired being discriminated against by insurance companies? This is a way more important story, or this 1 in 5 statistic would be a good lead in to why high costs of hearing aids impacts a LOT of people.

      Lexie can't wait until the health insurance community starts to call eye glasses a luxury item as well.
      It would seem in your situation if eye glasses are not an option they might slide the importance for you to compensate, but that would cut into insurance companies bottom line.

      My insurance company told me that my daughters hearing aids were cosmetic and therefore not covered. I often wonder if she got hit by a car that she couldn't hear coming...would that claim be cosmetic too. The whole subject makes me so crabby. My daughter was born with hearing loss...

    Lets see, well I worked in an engine room during my hitch in the nav.I fired a lot of rounds with my mini-14. I am a metal fabricator that uses a lot of loud power tools. I played in a thrash metal/punk band. I work in a club with a lot of live punk and metal bands. I love my ipod and my walkman before that. I wore ear plugs most of the time during all of that, but I now I have this constant ringing in my ear that sounds like a 1000 crickets. Oh yea Im 48 years old.

      Husband worked on the flight line most of his Air Force career, with hearing protection. Jet engine noise is usually the standard for "LOUD" in all the studies, so lots of our friends from those years have mid-high range hearing loss. So far he has lucked out and only has high frequency loss that the audiologist said is NOT connected to his flight line work.

      ACE, look into an electric lawnmower. Much, much quieter. Just be prepared to replace it when the battery finally won't hold a charge, the company who made ours stopped using the battery ours uses almost immediately after we bought ours and of course there are no replacements to be found. We had to go back to a gas powered one and are not happy.

      My heart goes out to you...I've had a hearing loss since the age of 5. Now, 27 years later, I've never had any health insurance coverage for my hearing aids. Luckily I've had parents who could afford my hearing aids. But with the growing number of baby boomers who need hearing aids, this should absolutely be covered by health insurance - it's a legitimate medical need, not a "want."

      So sorry, Nicole. It is scary! My son was misdiagnosed with permanent hearing loss at 3 months and again at 5 months. I had no idea how we'd pay for them at the last minute. There are TONS of programs out there to either pay for all of the aids or the majority of the cost. Check with your health department and talk to them about it. We had a fund from the state pay for our hearing aids, but the health department has a program that would pay for them and replace them however often as needed up until age 18 so long as we paid our part (which, based on my husband's income, was only $400). The income limits are generous. There is also the United Healthcare Children's fund which allows 5 or 10,000 over a lifetime for medical needs...it's just a gift...you apply for it, and hearing loss is one of the qualifying disabilities. Check it out.

    Published in the International Journal of Audiology
    Dental mercury amalgam fillings associated with a deterioration of high-frequency auditory acuity

    Hearing loss is by far the most common disorder of the senses, affecting more than 36 million people in the US alone. Mercury has been shown to affect the auditory system at a wide range of levels, from the cochlea to the cortex. In this study, compared were the number and surface area of different types of dental fillings with auditory thresholds in the range of .25 to 16 kHz. having more amalgam fillings was associated with a deterioration of high-frequency auditory acuity (8 kHz and above), independent of socio-economic factors. Thus, these results suggest a detrimental, dose-dependent effect of amalgams on hearing. There is also a likely duration-dependent effect. for more info visit mercuryexposure dot info

    Another cause of hearing loss can be high dosage chemotherapy with the drug cisplatin which I needed to save my life. I now must wear a hearing aid each ear at $3,000/ear. My husband has great health care through his employer, but they won't touch any part of this.Same goes for medicare. I guess hearing everything anyone says as gobbledygoop is perfectly acceptable. Not a health problem at all.

    Protect your hearing regardless of what other may think of you.

    – wear earplugs to concerts

    – use your fingers and plug your ears as firetrucks, ambulances, sirens pass by

    – keep your windows rolled up during heavy traffic and freeway driving

    – plug your ears with your fingers when kids are screaming around you and when DOGS bark

    I'm an audiologist. It's tragic to see so many people with hearing loss that could have been prevented. If you have a hearing loss, be sure to get it checked, since some conditions can be corrected without hearing aids. Unfortunately, if you have hearing loss from noise overexposure, the damage is usually permanent if it does not recover in a day or so.

    Yes and if you require hearing aids, don't be shocked at what insurance companies DON'T pay. They offer buy-up vision plans which help a great deal, but only a mere pittance for hearing aids. Why? Hearing is one of the five senses. Shouldn't it be considered as important as seeing, smelling, tasting or feeling? Nah, just turn on the "closed captioning". When insurance companies offer $300. 00 as a fair and customary price for $4000 hearing aids, they're way out of touch with reality...
