Most people, including most doctors, don’t know that noise causes both hearing damage–hearing loss, tinnitus and hyperacusis–as well as a whole host of non-auditory health problems, including hypertension, diabetes, obesity, heart attack, stroke, and death.

These non-auditory health effects are discussed in this article that reviews the current literature.

The European Union understands the dangers that noise exposure poses, and it is taking steps to protect the public via the Environmental Noise Directive.

If enough Americans make sure their elected representatives know that they are worried about how noise affects us, maybe the U.S. will become quieter and healthier, too.

How loud is too loud?

How loud is too loud? Probably between 70 A-weighted decibels (dBA) and 75 dBA, the auditory injury threshold, not the occupational noise exposure limit of 85 decibels cited in this article.

We are glad to see any publication warning about the dangers of noise and advocating use of hearing protective devices, as earplugs and earmuff hearing protectors are more broadly known, but this piece just gets the basic science wrong.

As the NIOSH Science Blog discussed in 2016, an occupational noise exposure limit is not a safe noise level for the public.

Smart phone sound level meter apps provide good to very accurate sound level measurements, but you really don’t need a sound meter to know if it’s too loud.

If it’s loud enough that you have to strain to speak or to be heard–a typical noise level when using power equipment or tools, hair dryers, kitchen mixers, or eating in many restaurants–the ambient noise is above 75 dBA and your hearing is being damaged.

And certainly if the sound level is loud enough to cause momentary pain or discomfort, or subsequent muffling or sound or ringing in the ears, you are on your way to hearing loss.

It’s easy to protect your hearing for your whole life. If it sounds too loud, it IS too loud.

Avoid loud noise or use hearing protective devices, or need hearing aids. The choice is yours.

The need for quiet

by Daniel Fink, MD, Chair, The Quiet Coalition

The Quiet Coalition’s Arline Bronzaft, PhD, is quoted in this article on one of the quietest places in the world, in today.com. It’s a thoughtful piece about the quietest room in the world, at least at first. But then the story unfolds and we learn about pervasiveness of noise pollution. Dr. Bronzaft, who is on hand to explain the effect of noise on health, notes, that “[y]our body does not get used to dealing with noise; it just adapts to it — but at a physical and mental cost.”

Click the link above to read the entire piece–it’s well worth your time.  For as Dr. Bronzaft points out, we all need a little (or a lot of) peace and quiet.

Another unintended consequence of global climate change

The Independent reports that Arctic whales are “threatened by collisions and noise pollution as ships begin crossing melting sea ice.” Among other things, the article tells us that whales are more vulnerable to this recent intrusion because “noisy ships interfere with their communication and cause fatal collisions.”

It’s almost as if humans are trying to see how quickly we can destroy everything on this planet.

Noise is bad for children

by Daniel Fink, MD, Chair, The Quiet Coalition

One of the nice things about doing a Google search is the serendipity of coming across something else.

I recently saw a mention of a World Health Organization statement that children shouldn’t be exposed to noise above 120 decibels, so I began searching for the source of that statement. While searching, I found this 2009 WHO PowerPoint presentation (pdf) about the adverse health effect of noise on children–not just hearing loss, but hypertension, increases in stress hormone levels, and difficulties learning, among a multitude of other adverse effects. Eventually, I found the 120 decibel recommendation in the WHO 1999 Community Noise Guidelines monograph.

It’s distressing that this information clearly has been known for so long–the pediatric noise hazards for almost a decade, the Community Noise Guidelines for almost two decades—and we still haven’t done anything to protect our children from noise.

With our first grandchild just born, I will renew my efforts to protect children and all people from the dangers of noise. I hope he grows up in a quieter world.

7 reasons to say no to fireworks

Lloyd Alter, the design editor for Treehugger.com, posted his annual rant about the dangers of fireworks.  In short, fireworks are a dangerous and stupid way to celebrate anything, and in exchange for the short-term pleasure of seeing things blow up in the air, here are the long-term consequences of using them:

They spew percholorates, particulates, heavy metals, CO₂ and ozone into the atmosphere, cause over 10,000 injuries a year, are cruel to animals, and can lead to hearing loss.

It’s not fun being a killjoy, but really, are fireworks necessary?

Does noise kill thousands every year?

by Daniel Fink, MD, Chair, The Quiet Coalition

This piece by Richard Godwin in The Guardian discusses the health dangers of noise exposure, including increased mortality. The dangers of noise are well-known in Europe, where the Environmental Noise Directive requires European Union member states to develop and implement government policies to reduce noise exposure for their citizens. Writes Godwin:

Noise exposure has also been linked with cognitive impairment and behavioural issues in children, as well as the more obvious sleep disturbance and hearing damage. The European Environment Agency blames 10,000 premature deaths, 43,000 hospital admissions and 900,000 cases of hypertension a year in Europe on noise. The most pervasive source is road-traffic noise: 125 million Europeans experience levels greater than 55 decibels – thought to be harmful to health – day, evening and night.

Somehow, this body of knowledge has yet to reach this side of the Atlantic Ocean, even though the overwhelming majority of experts think that the scientific evidence is strong enough to establish causality, not merely a correlation or association of noise and health problems.

I am confident that when the public does learn about the dangers of noise for health–not just causing hearing loss, but also hypertension, diabetes, obesity, heart attack, stroke, and death–Americans will also push their elected officials for laws and regulations to achieve a quieter environment.

More study needed on hearing loss among preschool teachers

by Arline L. Bronzaft, Ph.D., Board of Directors, GrowNYC, and Co-founder, The Quiet Coalition

As an educator, psychologist and researcher on the effects of noise on children’s learning, I have been long interested in the sounds to which children and teachers are exposed to in the classroom. While the literature is indeed plentiful on the dangers of loud sounds and noise to the hearing of young children, as well as to the impacts of noise to their cognition and learning abilities, and my own writings have noted that noise in the classroom disrupts teaching, little has been said about the impacts of loud sounds and noise to which teachers of young children are exposed.

Now we have this study from Sweden that has found hearing-related problems in preschool women teachers that is considerably higher than would be expected. I am looking forward to reading the published study of this paper to learn more about the methodology and specific findings but still, based on this report, would suggest that there be additional studies in other countries, including the U.S. If indeed these findings hold up, then the design of schools with a special emphasis on the acoustics must be given greater thought as the article suggests.

And better school design would also benefit the students. Groups of children tend to be noisy but even here the sound levels can be lessened with appropriate interventions and children can also be taught the importance of being quieter in reading sessions and at times when they read or draw on their own at their desks.

Dr. Arline Bronzaft is a researcher, writer, and consultant on the adverse effects of noise on mental and physical health. She is co-author of “Why Noise Matters,” author of “Listen to the Raindrops” (children’s book illustrated by Steven Parton), and has written extensively about noise in books, encyclopedias, academic journals, and the popular press.  In addition, she is a Professor Emerita of the City University of New York and Board member of GrowNYC.
