Noise pollution in Arizona

This podcast from Arizona Public Media discusses noise pollution in Arizona. The particular issue in the Tucson area is fighter jet noise from Davis-Monthan Air Force Base. A-10s are noisy but still quieter than F-16s. Residents are now concerned about the possible stationing of new F-35 jets, which are much louder.

The first half of the podcast is citizens explaining their noise problems in the Tucson area. The second have is an interview with The Quiet Coalition’s Richard Neitzel, PhD, on the faculty of the University of Michigan School of Public Health. Prof. Neitzel is heard at about minute 16 of the podcast, where he discusses the adverse effects of noise on health.

Aircraft noise pollution is well-studied as a health and public health hazard, and is known to cause hypertension and other cardiovascular disease and also interference with learning in schools located beneath flight paths. Do click to listen to the podcast, as it’s well worth your time.

Apple picks Dr. Neitzel to crunch its noise app crowdfunded data

Listen to this 12-minute interview (scroll down to the 6th story) on Michigan Public Radio with The Quiet Coalition colleague Richard Neitzel, PhD, at the University of Michigan! Dr. Neitzel has gotten a lot of press recently because he was picked by Apple Computer to analyze the stream of crowd-funded data on public noise exposure that Apple has started gathering via it’s new noise app on the iWatch and iPhone.

For those of us who have spent years piecing together the troubled and obscure four-decade-long history of public noise exposure and how it was swept under the rug, Dr. Neitzel’s interview brilliantly sums up both the history of what happened and the tipping point that is occurring now—thanks in part to the availability of
crowd-sourced data from research tools that have never been available to epidemiologists before, namely, the new noise app on Apple’s iWatch and iPhone.

We hope we can put the troubled history of the noise issue behind us and look forward to brighter—and quieter—future thanks to Apple and Dr. Neitzel’s team who will
be watching and interpreting this data.

RECOMMENDATIONS TO REDUCE HEARING LOSS FROM RECREATIONAL SOUND EXPOSURE

This detailed review article by Richard Neitzel, PhD, and Brian Fligor, PhD, in the Journal of the Acoustical Society of America discusses the risk of noise-induced hearing loss from recreational sound exposure.

The abstract contains the important conclusions, which are amply supported by the article itself. They are:

  1. The recommended occupational exposure limit is 85 A-weighted decibels (dBA)*. Some exposed workers will develop hearing loss from this noise exposure. To eliminate the risk of hearing loss, a 24 hour average of 70 dB is recommended.
  2. It is possible that occupational noise exposure may have worse impacts on hearing than equal exposures to recreational noise. But the application of statistical hearing loss models developed from occupational noise data to estimate the impacts of recreational noise exposure is nevertheless warranted.
  3. A recreational noise exposure limit of 80 dBA for 8 hours, equivalent to 75 dBA for 24 hours, should prevent hearing loss for adults. For children and other vulnerable individuals, e.g., those who already have hearing loss, the lower exposure level of 75 dBA for 8 hours, or 70 dBA for 24 hours, is appropriate.

Common non-occupational noise exposure sources include public transit, appliances, power tools, personal music players and other personal listening devices, musical instrument practice and performance, concerts, sports events, and parties.

Protecting hearing is simple. Eliminate high noise exposures where possible, increase the distance between you and noise sources around you, and use hearing protection (earplugs or ear muffs).

Because if something sounds too loud, it is too loud, and your hearing is at risk.

Mainstream media finally discover noise

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

We’re delighted that The Quiet Coalition co-founder and distinguished scientist Richard Neitzel, PhD, of the Univ. of Michigan School of Public Health, is cited in the recent issue of Woman’s Day magazine.

Rick’s research is well known at respected national and international agencies like the Centers for Disease Control and Prevention and the World Health Organization. Those are powerful but small audiences. But his appearance in Woman’s Day magazine–with its circulation of 3.4 million American households–indicates that the health effects of noise are becoming a “mainstream” issue, one that the popular press and its millions of readers are beginning to hear about above the “noise” of all the other contentious, interesting and competing subjects they have to cover every week.

That’s progress! And it’s because of rigorous, independent research by people like Dr. Neitzel that media outlets are paying attention. Kudos Rick!
