Doctors with disabilities? Yes, we are people too

by Daniel Fink, MD, Chair, The Quiet Coalition

This piece from NPR discusses how doctors and researchers with disabilities are changing medicine. When a problem is a secret, it is a source of shame and can’t be dealt with. If it is disclosed and discussed, however, it may still be a problem, but it can be dealt with and it is less of a source of shame.

When I spoke at the 2017 meeting of the Institute for Noise Control Engineering in Grand Rapids, Michigan, across the river from the Gerald R. Ford Presidential Library, I noted that his wife Betty Ford was a pioneer in discussing two formerly kept secrets–that she had breast cancer and had developed an addiction to prescription drugs. She fortunately survived her breast cancer to live many years more, and successfully dealt with her addiction. I then noted that I would publicly disclose that I had two auditory disabilities, tinnitus and hyperacusis, both fortunately mild and not life-limiting, but disabilities nonetheless.

I have mild hearing loss, too, again fortunately not life-limiting except in terms of understanding speech in a noisy environment.  Prof. Margaret Wallhagen in San Francisco has written about the stigma of hearing loss. Hearing loss should be destigmatized.

More importantly, noise-induced hearing loss should be prevented.

So avoid noise or use hearing protection if you can’t avoid it, because noise-induced hearing loss is 100% preventable.

Sound regulation of unnecessary noise

Once again another community has come to the conclusion that fireworks noise must be controlled to protect wildlife. This time enforcement has come after a horrific reaction to a New Year’s fireworks display. Namely, Devon council in the UK will enforce a noise limit on fireworks after a New Year’s display startled nearby birds resulting in death for hundreds of them.

As we reported before, quiet fireworks exist. It is simply irresponsible for communities to continue to torment animals because they want loud noise to accompany what is primarily a visual display.  Then again, considering the pollution fireworks cause, can we just move on to something else that isn’t as destructive?

How much time should you spend in nature each week?

by Daniel Fink, MD, Chair, The Quiet Coalition

This article in the New York Times discusses time spent outdoors as something important to health. From a study done in the UK, researchers concluded that two hours a week was sufficient, with less time conveying little benefit but more time conveying no additional benefit in terms of health or perceptions of health.

Why is time in nature important? No one is sure. Green spaces especially seem to help. I think on important component of the nature experience is that nature is generally quiet, with few loud sound sources and trees and grass helping to absorb, rather than reflect, any loud sounds that might intrude.

Of course, that assumes one turns off one’s personal music player.

Apple watch to add noise monitoring

Apple has announced that it is adding a noise monitoring feature to the Apple watch. The new feature should be available in late 2019. Users will be able to set their own sound warning level (according to this French-language link), but the example used in the linked Mic article cites 90 decibels (dB) as the warning level.

That’s too loud.

The World Health Organization recommends a daily average noise exposure of only 70 decibels to prevent hearing loss. After only 30 minutes at 90 dB, one has reached that daily noise dose even if the other 23 1/2 hours have zero noise, which is impossible.

Most people don’t know that the auditory injury threshold, the threshold at which auditory damage begins, is only 75-78 A-weighted decibels* (dBA) for 8 hours, which mathematically is the same as 70 dB time-weighted average for 24 hours, or 85 dBA for only 1 hour. There is some evidence that auditory damage may begin at sounds as low as 55 dBA for 8 hours. The only evidence-based noise exposure level to prevent hearing loss is a time-weighted average of 70 decibels for 24 hours.

If you have an Apple watch and want to use the noise monitoring feature, we suggest setting the alarm level at 80 or at most 85 decibels.

But you don’t need an Apple watch or a sound level meter app on your smart phone to know if you’re being exposed to too much noise. If you have to strain to speak or be heard in a normal conversation at the usual 3-4 foot social distance, the ambient noise is above 75 dBA and your hearing is at risk.

Protect your ears now, or need hearing aids later.

NYC helicopter crash shows risks of Uber’s “urban air-taxi” fantasy

Today, The New York Times reported on a helicopter crash atop a midtown Manhattan skyscraper that left one person dead. The copter exploded, presumably throwing debris onto the streets below, though there are no reports of injuries on the streets below. One hundred emergency workers were called out.

We’ve written about the enthusiastic visions promulgated by Uber, NASA and others, for vast fleets of small “inter-urban air taxis” that use vertical take-off and landing. My concern, of course, is the increase in noise implied—even if these “air taxis” are electrically propelled. But the accident reported today shows the significant risk of crashes and potentially lethal debris falling on people in the streets below.

Last October, the 36-member Congressional Quiet Skies Caucus celebrated a significant achievement: passage of the FAA Re-Authorization Act which included several important clauses concerning the national problem of aircraft/airport noise. The reason we wrote about the Uber/NASA’s “air taxi” fantasy was because we hoped this group of members of Congress would realize that the battle to reduce aircraft noise and other dangers has now expanded to include roof-top heliports in densely populated urban centers like Manhattan, from which this next generation of small, electric VTOL aircraft could be deployed sometime in the near future.

The Congressional Quiet Skies Caucus needs to get back to work on this problem before Uber’s fantasy becomes our reality!

How to minimize your noise footprint

by Daniel Fink, MD, Chair, The Quiet Coalition

I hadn’t thought about how much noise I make–I’m pretty sure I don’t make much except occasional hammering and power tool use when doing yard and household maintenance–until I read this article by Paige Towers in The Guardian that introduces the concept of a person’s noise footprint.

We talk about our carbon footprint and what those concerned about climate change can do to try to reduce theirs, but we should think about how much noise we make, too. The amount of carbon dioxide and related substances each person produces from fossil fuel use affects the world, including humans and animals.  So does the amount of noise we each produce.

As Ms. Towers points out, some noise production is inevitable, but if we have a choice to use a quieter alternative, we should make that choice. And her call for noise activism is exactly what I’ve encouraged for years.  If we all do our part, the world will be a quieter, healthier place.

Want a quieter town? Urge local government to “Buy Quiet”

by David M. Sykes, Vice Chair, The Quiet coalition

These two 5-minute videos from the U.S. Centers for Disease Control and Prevention spell out how business owners can reduce noise-induced hearing loss by creating “Buy Quiet” programs as a first step when purchasing or renting machinery or tools.  The Buy Quiet program “encourages companies to purchase or rent quieter machinery and tools to reduce worker noise exposure” when they first start up or when older machinery and tools are replaced. You can make your town or neighborhood quieter by getting your local government to encourage it’s own departments–as well as area businesses–to Buy Quiet.

Buy Quiet programs originated at NASA, where they were concerned about astronauts who, it turns out, were exposed to excessive and dangerous noise level when they were floating around in space.

But Buy Quiet gradually expanded to other federal agencies, for instance the National Park Service, eventually reaching the CDC, which realized that exposing the public to excessive noise levels from construction, traffic, airports, etc. was actually a dangerous public health problem. At that point, the CDC and other federal agencies began publishing the kind of public education materials linked above and much more.

It’s time for all of us to take the noise problem seriously. Remember, as our chairman Dr. Fink says, “if it sounds too loud, it IS too loud!”

London subway noise is excessive

by Daniel Fink, MD, Chair, The Quiet Coalition

This article in the London Post reports that loud noise on 37 London Underground routes exceeds 85 dB. The World Health Organization recommends only one hour of 85 A-weighted decibel noise exposure to prevent hearing loss. The UK’s Health and Safety Executive recommends posting of warning signs if the noise exceeds 85 decibels. Despite this, Transport for London, the agency that operates London’s subway lines, states that it believes “Health and Safety Executive guidance suggests Tube noise is highly unlikely to cause long-term hearing damage.”

They’re wrong. If one’s commute is 30 minutes or greater each way, the total daily exposure from subway noise alone exceeds the WHO’s safe noise exposure level to prevent hearing loss. And, of course, the Londoner is undoubtedly exposed to other noise sources, such as loud music in restaurants and shops.

When I visit London, I wear earplugs when taking the Tube. You should, too.

Because if it sounds too loud, it IS too loud!

Loud restaurant noise drives away people with auditory disorders

This article by Marcella Bernanrdo, from the Vancouver CityNews, reports that loud restaurant noise is driving away people with hearing loss, because they can’t understand speech in noisy environments.

Ambient noise is a disability rights issue for those with auditory disorders. Right now, both the Canadian and U.S. economies appear strong and restaurants are busy, so no wonder restaurateurs see no need to make restaurants quieter even though restaurant noise is a major complaint even for those with normal hearing.

Given the lack of economic incentive, it will likely require legal action under disability rights law, or local action by dedicated activists demanding ordinances regulating noise, to make restaurants quieter.

I say there is no time like the present–get online, find your local politician, and ask him or her where they stand on noise.

Is a personal noise alert system needed?

Silencity received a comment to my recent blog post about hearing protection asking if a noise alert system could be developed to let people know when they were encountering dangerous noise levels.

There are wall-mounted devices available, but I don’t know of any personal noise warning device, either for occupational use or for the public. Such a device or smartphone app would be nice but I don’t think it’s needed. Why?

For some time I have been ending posts with the line, “If it sounds too loud, it IS too loud.” And that advice is why one doesn’t need a noise alert system. If you think a noise is too loud, you’re probably right.

For sure, if a noise hurts your ears, even if it doesn’t bother someone else, it’s too loud for you.  There are clearly variations in sensitivity to noise, but you need to protect your hearing, not someone else’s.

And if a noise exposure causes temporary ringing in the ears or muffling of hearing, that’s a definite sign that the noise was too loud.

For noise levels that aren’t quite that high, a simple and easy rule of thumb is that if you can’t carry on a conversation without straining to speak or to be heard, the ambient noise is above 70-75 A-weighted decibels.

And that’s why you don’t need a noise warning device. Depending on your belief system, God, Mother Nature, or Darwinian evolution already gave you one!
