This article in The New York Times details ten years of regulatory dithering while millions of young people became addicted to nicotine through vaping. The health dangers of vaping were clear to many, but political considerations, lawsuits, and perhaps an early lack of clear evidence of harm led to inaction. And now young people, and a few older ones, are being sickened with several dying.

I see a similar situation developing with the widespread use of personal music players by young people.

The Sony Walkman was marketed in 1979, the iPod in 2001, and the now ubiquitous iPhones in 2007 and Androids in 2008. A large number of Americans use personal music players, and surveys find that users listen for several hours a day.  This report citing Nielsen figures says that Americans listen to music 32 hours a week!  That’s 4.5 hours every day. The World Health Organization recommends listening to no more than one hour daily, to prevent hearing loss. Other studies show that some users typically listen to music at high volumes, loud enough to drown out ambient noise.

There has been some media coverage about prolonged exposure to personal music players, but most people don’t seem to be aware of the problem.

I have communicated with the Federal Trade Commission’s Division of Advertising Practices, the Consumer Product Safety Commission, the National Institute on Deafness and Other Communication Disorders, and the Centers for Disease Control and Prevention about what I see as a future epidemic of noise-induced hearing loss when today’s young people reach mid-life, after 30-40 years of excessive noise exposure. The CDC has begun a research program into noise and the public and undertaken educational efforts about the dangers of noise on hearing, but as with vaping devices, it’s clear to me that regulatory action is needed and that’s not something CDC does. Education can help change health behaviors, but regulation is much more effective.

Will there be media reports in 2030 or 2040 about the lost opportunity to prevent the epidemic of noise-induced hearing loss? I wouldn’t be surprised if there were.

Unfortunately, then it will be too late to prevent the epidemic of noise-induced hearing loss. The time for action is now.

Yahoo Lifestyle reports on the 20 breeds of dogs you should consider if you want to adopt a dog, but can’t deal with the noise.

We couldn’t help but notice that one of the suggested breeds is Pekinese, and we recalled–not with fondness–a former neighbor’s Pekinese that surely was the exception. So take the list with a grain of salt, but know that there are options for sound sensitive–and considerate–dog owners.

Why is the world so loud?

This wonderful article in The Atlantic discusses a specific noise issue in Arizona as well as noise pollution generally. In the piece, we are introduced to Karthic Thallikar, an Arizonan who became aware of a low hum in his neighborhood and went on a two-year quest to discover the source. The approach in The Atlantic article is a bit different from that in a recent article in The New Yorker on noise pollution, but both articles are worth reading.

Recently, with the help of several noise colleagues, I recently developed a new definition of noise: noise is unwanted and/or harmful sound. Specific noise levels adversely affecting human health and function can be found in my article in the Fall 2019 issue of Acoustics Today, “Ambient Noise is the New Second-hand Smoke.”

I am encouraged that the mainstream media are examing noise pollution and its adverse effect on health, as there can be no rational doubt that noise is a public health problem. I hope you will join me in working towards making our world a quieter place that is better for all living things.

In their defense, they just wanted some sleep

Angry Edinburgh residents, enraged by unending road work noise, pelted workmen with baked beans, haggis.

While the reaction may seem unwarranted, Stian Alexander, reporting for the Daily Record, writes that the drilling only ends at 11:00 p.m. and the noise continues as work doesn’t end until 3:00 a.m. The bosses at the City of Edinburgh Council are undeterred by the residents protest, however, as the work–and noise–will continue for at least another week.

Genetic susceptibility to hearing loss from noise exposure

by Daniel Fink, MD, Chair, The Quiet Coalition

This article in The Hearing Journal reviews research on genetic susceptibilities to hearing loss from noise exposure. The author notes that 34 genetic variants have been reported to show an association with increased susceptibility to hearing loss from noise exposure. She concludes that “[f]urther work on the genetic and cellular bases of NIHL could enable the characterization of individual susceptibilities and help prevent this widespread disease.

Actually, additional work isn’t needed to help prevent noise-induced hearing loss (NIHL).  Additional research is always good, but the molecular bases of NIHL are very well understood.

Even better understood is how to prevent it: Avoid exposure to loud noise, leave the noisy environment, or wear hearing protection of one can’t do either. The CDC states that NIHL is 100% preventable.

Because noise exposure causes hearing loss, and if something sounds too loud, it is too loud.

Starting January, help comes to the hard of hearing at your local drug store

This New York Times article is a wake-up call to all Americans with hearing loss: Starting January 2020, and for 1/10th the price of conventional–and ugly–hearing aids, you can buy “hearing assistive devices” at your local drug store or directly online. The innovation economy has finally come to the hidebound hearing aid industry!

And we can thank a genuinely bi-partisan team in Congress for making this happen. Charles Grassley, Republican from Iowa, and Elizabeth Warren, Democrat from Massachusetts, teamed up in late 2016 to write the “Over the Counter Hearing Aid Act,” pushed it through both houses of Congress, and in 2017 convinced President Trump to sign it.

Thank you Senators Grassley and Warren!

What this Act does is tell the FDA to keep its regulatory hands off of a new class of hearing-assistive devices called “personal sound amplification products,” or PSAPs. PSAPs are miniaturized, multi-featured wireless high-tech in-ear devices that do lots of things conventional hearing aids don’t do, and all for about 1/10th the price of conventional hearing aids.

Maybe deregulation works after all!  In this case, it’s good-old-fashioned bi-partisanship that got the deal done.

So if you or a loved one really need hearing aids but haven’t been able or willing to spend the $5,000 to $10,000 the hearing aid cartel has been charging, now’s your chance to tune into the world of sounds you or they have been missing. Check it out!

A revised definition of noise for National Protect Your Hearing Month

October is National Protect Your Hearing Month, and I am using the occasion to propose a revised definition of noise: noise is unwanted and/or harmful sound.

For many decades, noise has been defined as “unwanted sound,” a phrase usually attributed to the late acoustics pioneer Leo Beranek. The problem with this definition is that it implies that the perception of noise is subjective. This means that those complaining about noise have no real basis for their complaints, other than a personal reaction to noise.

The new definition acknowledges that noise can be harmful to human health and can interfere with human activity. Even if a noise is merely unpleasant, that experience is stressful.  Recent research shows that stress causes vascular inflammation and cardiovascular disease.

The revised definition is supported by my article in the Fall 2019 issue of Acoustics Today, summarizing the evidence-based noise levels affecting human health and function. My article makes it clear that there can be no rational doubt that noise is harmful, and unwanted noise especially so. Sounds as quiet as 30-35 A-weighted decibels (dBA) can disrupt sleep. A good night’s sleep is important for health and function. Forty-five decibel (dB) sound can disrupt concentration and interfere with learning. At 55 dB, non-auditory health impacts of noise begin, including hypertension, cardiovascular disease, and increased mortality. These effects are best studied for transportation noise, but are seen with occupational noise exposure. At 60 dBA ambient noise, people with hearing loss have difficulty understanding speech. At 70 dBA, those with normal hearing also have difficulty understanding speech.

Seventy dB time-weighted average for 24 hours is the only evidence-based noise exposure level to prevent hearing loss, but the actual safe noise level is probably lower than that. And 85 dBA is the occupational recommended noise exposure level, not a safe noise level for the public. And as I notedin my article, the World Health Organization recommends only one hour exposure at 85 dBA daily to prevent hearing loss. Because the decibel scale is logarithmic, this is mathematically the same as 70 dB time-weighted average for a day.

Hearing loss is very common in older people, but I’ve learned that this isn’t part of normal physiological aging. Rather, presbycusis or age-related hearing loss is largely noise-induced hearing loss.

So what can you do to protect your hearing? There are two ways to protect hearing: avoid loud noise, and if you can’t, use hearing protection devices.

We only have two ears, and unlike knees they can’t be replaced. So if a noise sounds too loud, it IS too loud. And if a noise is so loud that one can’t converse without straining to speak or to be heard, the ambient noise is above 75 dBA and your hearing is at risk.

And always remember that noise is unwanted and/or harmful sound

A call for quiet fireworks

As Guy Fawkes day approaches ushering in bonfire season in the UK, a Bradford city councillor has called for the council to consider making a law to restrict loud fireworks displays and require quiet ones.

We have written about quiet fireworks before, noting that noise is part of the design of traditional fireworks. But as Councillor Jeannette Sunderland asserts, “[t]he manufacture of fireworks has progressed and it is now possible to hold displays and events of quieter fireworks which can create ‘quieter’ displays, ‘low noise’ displays or silent displays which reduce the noise nuisance and impact on others in terms of acoustic stress.”

It’s not impossible to remove some noise from our lives without giving up things that people enjoy.  Fireworks are, primarily, a visual display.  While there are those who may love the noise that accompanies the brilliant display, by limiting it the experience can be enjoyed by many more people.

Then again, if we consider the overall impact of a fireworks display, maybe it’s time to move on to something a bit less destructive.

The quest for quiet dining

This piece by Brooke Randle in the Mountain Express, Asheville, North Carolina, discusses the problem of restaurant noise.

There’s nothing really new in Randle’s story, but any report that spreads the word about the problem of ambient noise in restaurants is important.

Because if a restaurant sounds too loud, it is too loud. And if enough people understand this, and complain to their elected representatives about restaurant noise–as we did about being forced to breathe secondhand smoke in restaurants in the 1980s and 1990s–eventually restaurants will be required to be quieter, just as they are now required to be smoke-free.
