Reducing the risk of noise-induced hearing loss (NIHL) isn’t rocket science. It’s actually quite simple: avoid loud noise exposure and if you can’t do that, wear hearing protection.

This piece from Hear It Now, which claims to be the world’s #1 website on hearing and hearing loss, has a nice summary of practical tips. Click the link to see the full list of tips. Your ears will thank you!

Despite impacting 48 million Americans, noise-induced hearing loss (NIHL) has languished in the shadows for decades. But that’s changing! Check out the 17-page beautifully illustrated article in the September issue of Real Simple magazine*, a Time/Life publication with 8.5 million readers nationwide (that’s eight times larger than the New York Times readership of 1.1 million).

If you’ve been looking for a “quick overview” you can hand to friends and family who fail to understand America’s unrecognized problem with hearing loss—whether it’s your kids’ and their constant earbud (ab)use, friends who can’t understand conversations when you’re dining out, or an elderly relative who’s stopped paying attention and is increasingly depressed—this article should get the conversation started. And if they ask “what else can I read about this?” Tell them to look at this issue of Scientific American, new information from the Centers for Disease Control, and this one-page Fact Sheet on the health effects of noise that The Quiet Coalition (TQC) published in 2016.

It’s clear that NIHL is, as TQC’s chair, Daniel Fink, MD, says, “a growing problem in America nearing epidemic proportions.” But there’s a lot of work to do to get people (including the nation’s leaders) to understand that this is a legitimate public health problem. Frankly, the European Union and Asia are far ahead of us on this issue.

In the meantime, take heart: major media are beginning to notice! Congratulations to the editor of Real Simple for recognizing this growing health crisis. We are extremely grateful that her magazine cited three of TQC’s Steering Committee experts in this piece–Rick Neitzel, PhD, Arline Bronzaft, PhD, and Bradley Vite–and also
described two practical success stories. We hope Real Simple will continue to cover this issue and give it the attention it deserves.

We have only one complaint: the magazine erroneously states that 85 dB is the threshold of hearing damage. In fact, research has shown that permanent hearing damage starts at noise levels as low as 75 dB; furthermore, non-audiological health effects, such as cardiovascular effects, can be caused by noises as low as 55 dB.

Attention commuters: put down your earbuds!

A recent article in The Hearing Journal should give pause to mass transit commuters who use personal listening devices (PLDs) to mask background noise. Michelle Brady, AuD, Suzanne Miller, PhD, and Yula C. Serpanos, PhD, write that “[m]ass transit commuters are regularly exposed to excessive noise levels,” and note that use of PLDs “adds further stress on the auditory system as commuters listen at high volume levels to mask the background noise encountered during their daily commute.” By cranking the volume in areas of high noise, they note, commuters are “creating further risk of noise-induced hearing loss” (NIHL).

What makes NIHL insidious is that it “occurs in stages across several years,” and “[a]s such, its effects often go unnoticed.” Until they can’t be ignored, of course. The authors conducted a study on New York City commuters and found that “mass transit commuters in NYC do not completely understand the consequences of hearing loss and the proper use of PLDs.” They conclude that hearing health professionals need “to do a better job at educating the public about the risks of NIHL and safe listening habits.”

We agree that people need to be aware of the risks of NIHL, but also think there should be a role that government must play to protect citizens. And, of course, PLD manufacturers need to work with medical professionals and government to design safe PLDs that won’t deafen a generation.

 

Treating hearing loss may help prevent dementia

By Daniel Fink, MD, Chair, The Quiet Coalition

A recent Canadian newspaper article discussing a report in The Lancet, the premier British medical journal, about preventing dementia.

The Lancet article highlights the importance of treating hearing loss for possibly preventing dementia. If you’re interested in dementia, know someone with dementia, or want to see what you can do to avoid developing dementia yourself, I recommend the Lancet article. It summarizes a large body of research in a readable fashion that should be accessible even to the lay reader.

There are many factors correlated with dementia risk, including genes, blood lipid levels, and diseases or conditions such as diabetes, hypertension, obesity, and factors such as social isolation and cigarette smoking. The association between hearing loss and dementia is well-known and research is under way to see if treating hearing loss reduces the risk of dementia. Despite only correlations, and no clear understanding of how hearing loss may increase the risk, the Lancet authors think the scientific evidence is strong enough to recommend treatment of hearing loss as a possible prevention measure for dementia.

Of course, the only treatment for hearing loss is hearing aids, with cochlear implants reserved for the more severely impaired. We think that people with hearing loss should use hearing aids just to be able to hear others, whether hearing aids prevent dementia or not.

That said, hearing aids are a poor substitute for preserved natural hearing.

Perhaps the Lancet article should have gone a step further and highlighted the importance of preventing noise-induced hearing loss (NIHL) to delay or avoid the onset of dementia. After all, we think it’s significantly better to prevent NIHL than to treat it, and that’s simple: avoid exposure to loud noise or wear ear protection when you cannot.

Experts: Hearing loss is on the rise among young adults

and their personal audio devices may be at least partially to blame. Melanie Campbell, a professor of Rehabilitation Medicine at the University of Alberta, warns that young adults “may be destined to swap out their headphones for hearing aids.” The problem is that this cohort “particularly loves music, they love it loud and they have very few worries about the future.” Campbell notes that World Health Organization statistics show that “[m]ore than one billion young adults are at risk of hearing loss,” and “[a]mong people aged 12-35 years, almost half are exposed to dangerously high levels of noise from personal audio devices like headphones while four out of 10 are exposed to unsafe levels of sound at concerts and other entertainment venues.”

According to Campbell, the primary cause for this hearing loss these days is noise-induced hearing loss (NIHL). What makes hearing loss particularly insidious, is that people generally don’t lose their hearing overnight. Instead, says Campbell, “[i]t creeps up and you gradually forget that you’re not hearing the door squeak, or you don’t hear people’s heels on the floor.”

To give young Canadians the information they need to protect their hearing and prevent hearing loss, Campbell has been promoting Sound Sense, a project led by the Hearing Foundation of Canada that spreads awareness about hearing loss in Canadian schools.

Spreading awareness about NIHL and how to prevent it is, of course, the the best option. Every school in the U.S. should regularly test students’ hearing and include information about NIHL in their health education programs. Given that NIHL is 100% preventable, the failure to educate children about how they can avoid NIHL is as insidious as the disorder.

 

Red wine and dark chocolate can protect against hearing loss?

Sign me up! Ok, a red wine and dark chocolate diet may sound pretty fabulous, but obviously one cannot embrace it as a way of life no matter how concerned you are about your hearing. And, in any event, Debbie Clason’s post at Healthy Hearing adds that while “a glass or two of red wine can guard against the type of inflammation that causes [noise-induced hearing loss], excessive drinking deposits toxic levels of alcohol in your bloodstream which can permanently damage your hearing.” As for the protective benefits of dark chocolate, it’s not the chocolate in dark chocolate that protects hearing.  Rather, chocolate “contains zinc, which is known for boosting the immune system and guarding against infections that plague the ear.”

So, as with most other things, enjoy some red wine and dark chocolate in moderation.  And who knows?  It may actually help to protect your hearing.

The CDC issues report on noise-induced hearing loss

and the facts are frightening. The Centers for Disease Prevention and Control’s (CDC) current issue of Vital Signs focuses on the dangers of noise on hearing health.  Among other things, the report states that:

  • 40 million Americans aged 20-69 years old have noise-induced hearing loss (NIHL). Hearing loss is the third most common chronic health condition in the US, and almost twice as many people report hearing loss as report diabetes or cancer.
  • 1 in 2 American adults with hearing damage from noise did not get it exposure to noise at work. Noise outside of work can be as damaging as workplace noise.
  • Too much loud noise, whatever the source, causes permanent hearing loss.
  • 1 in 4 Americans who report excellent hearing have hearing damage.  You can have hearing loss without knowing it.
  • The louder the sound, and the longer you are exposed to it, the more likely it will damage your hearing permanently.
  • Continual exposure to noise can cause stress, anxiety, depression, high blood pressure, heart disease, and many other health problems.

This fascinating if distressing report comes with easy to understand graphs and charts that clearly explain the dangers of noise exposure, who is most at risk, the high cost of hearing loss, how hearing loss occurs, and, most importantly, what can be done to prevent NIHL.  Because, in the end, one point is crystal clear: noise-induced hearing loss is 100% preventable.

Have kids? Protect them from a preventable health threat:

The Starkey Hearing Foundation has launched Listen Carefully, a campaign to raise awareness about noise-induced hearing loss.  The campaign was started to combat a growing public health threat.  Namely, that “one in six American teens has noise-induced hearing loss from loud sounds.”  The Foundation wants to alert the public to this health threat and prevent a hearing loss epidemic.

Go to the Listen Carefully website to learn the facts about noise-induced hearing loss and find out how you can get involved to stop it.

Maybe this will get peoples’ attention:

AC/DC’s Brian Johnson quits touring for good because of hearing loss.

Yes, nothing like the threat of complete hearing loss to bring home the importance of protecting one’s ears.  Let’s hope that AC/DC considers the damage inflicted on concert goers when they resume touring.

Safe noise exposure for the general public

Daniel Fink, M.D., Interim Chair of the Quiet Communities Health Advisory Council, has written a post for the Quiet Communities’s blog that tackles a question which is rarely addressed: What noise level IS safe for preventing hearing loss?

In his post, Dr. Fink discusses the seeming contradiction between a 1974 Environmental Protection Agency (EPA) determination that “a 24-hour average noise exposure level of 70 decibels (dB) or less prevent[s] measurable hearing loss over a lifetime” with statements from various governmental and nonprofit organizations that suggested that “a much louder noise level − anything up to 85 dB − was safe for our ears.”  In the course of researching the issue, he received a communication from the National Institute of Occupational Safety and Health (NIOSH) that explained where the 85 dB figure came from; the information in that communication formed the basis of a post on NIOSH’s Science Blog in February 2016 (which is discussed here).

Long and short, the NIOSH communication explained that the 85 dB was an occupational noise exposure standard developed to protect workers over a lifetime of work, whereas the EPA determination of 70 dB averaged noise exposure over 24 hours was believed to protect the general public from hearing loss over a lifetime.  As Dr. Fink notes that the clarification of the difference in noise exposure limits is important in setting public policy and protecting public health, and he concludes that, based on his research, “[t]he much lower 70 dB average noise exposure level is the only published safe noise level to protect the public’s hearing.”
