What is a safe noise exposure level for the public?

What is a safe noise exposure level for the public?

That seems like an easy question, but the answer wasn’t obvious in 2014 when I became a noise activist, trying to make the world a quieter place. My interest was in preventing auditory disorders. (I’ve since learned that noise has non-auditory health effects, too, at lower noise levels, but my focus always is on auditory health.)

The internet didn’t help much. Most links found used the 85 decibel (dB) standard, because the National Institute on Deafness and Other Communication Disorders stated, and still states, that “[l]ong or repeated exposure to sound at or above 85 decibels can cause hearing loss.” This didn’t seem right to me, because I have hyperacusis and sound levels much over 75 dB hurt my ears.

It took me a year to learn that the 85 dB standard comes from the NIOSH noise criteria (pdf) and isn’t a safe noise level for the public, and not for workers, either.

Now, when one searches for “safe noise level” or “safe noise level for the public,” the overwhelming majority of links cite my several publications on this topic. As I have written, the only evidence-based safe noise exposure level to prevent hearing loss is a time-weighted average of 70 dB for 24 hours, but for a variety of reasons the real safe exposure level has to be lower.

The 85 dB standard lives on, zombie-like, refusing to die, but at least accurate information about the safe noise level to prevent hearing loss is now widely accessible.

I hope accurate information about safe noise levels will empower the public to demand quiet, before we all lose our hearing.

Information is our weapon against noise

As this column by Jane Brody discusses, 47 years ago the Center for Science in the Public Interest started informing the public about good nutrition and also influencing public policy about food labeling and nutrition standards.

CSPI’s success has been mixed, but it clearly has had a major impact.

I didn’t realize it at the time, but when I became a noise activist three years ago–after reading this article in The New York Times science section about hyperacusis, which I have–I set out to do the same thing for noise that CSPI has done for food and nutrition.

Everything I do regarding noise is based on scientific and medical evidence. To my surprise, most of the information I have written about has been known since the early 1970s, or even earlier. It just has been forgotten since the Environmental Protection Agency’s Office of Noise Abatement and Control was defunded (pdf) during the Reagan years. I took me a year to learn what a safe noise level is, as I wrote in the American Journal of Public Health. [Hint: it’s not 85 decibels without time limit, as the National Institute for Occupational Safety and Health insists on its website, with the misleading statement “[l]ong or repeated exposure to sound at or above 85 decibels can cause hearing loss.” That’s true, but it’s like the National Cancer Institute saying, “standing out in the sun every day for a long time all summer long can cause skin cancer.”]

So let’s hope that regulators and policy makers will begin to recognize the dangers of noise exposure in the new year. I’m certainly going to do my part to bring this problem to their attention. I hope you will join me.

First mobile app for street-level air and noise pollution launches in Europe,

coming to the United States soon.  According to its developers, the Ambiciti mobile app “measures levels of air and noise pollution street by street in real-time and offers the healthiest route for urban citizens to move and live in their cities.”  The app does this by combining “all sources of information available: numerical simulations, observations of fixed sensors, mobile sensor observations and qualitative observation,” so that people can choose a path around the city that minimizes their exposure to noise or air pollution.  The developers hope that the information the app provides influences policy decisions and encourages healthier lives.
