Sound and the city

This excellent essay by on Curbed discusses urban noise levels. It’s a very comprehensive piece, discussing multiple aspects of urban noise and how it affects people.

Some urban noise is an unavoidable accompaniment to modern life, but much can be done to make cities quieter. These include enacting laws against excessive vehicle exhaust noise, horn use, aircraft noise including helicopter flights, and indoor quiet laws.

Of course, enacting laws isn’t enough. They must be actually be enforced. Crowdsourced reporting using smartphone apps can help with enforcement.

My only quibble with the Curbed article is that the author cites the Centers for Disease Control and Prevention as recommending only 85 decibels (dB) for 8 hours to prevent hearing loss, but the link is to the National Instititue for Occupational Safety and Health. While part of the CDC, NOISH is charged with making recommendations for the prevention of work-related injury and illnes, not recommendations for the general public. So NOISH’s 85 dB exposure standard, actually 85 dBA*, is an occupational noise exposure level to prevent noise-induced hearing loss in the workplace–it’s not intended to be a safe exposure threshold for the public.

The NIOSH Science Blog post on February 8, 2016, specifically addressed this concern. And my research revealed that the only evidence-based safe noise level to prevent hearing loss is an average of 70 decibels a day.

Given the general misunderstanding of what is a safe noise exposure level for the average person, Furseth’s article raises important issues that I hope are starting to be taking seriously.  Cities have gotten louder and the effect of increased noise on residents and visitors is something that should be given serious attention.

San Franciscans press their congresswoman to arrest airport noise

Congresswoman Jackie Speier, who is featured in this Curbed article, is one of 16 members of California’s Congressional delegation who are actively involved in the 47-member Congressional Quiet Skies Caucus. Her San Francisco constituents have a strong chapter of the the Caucus’s regional support network, The National Quiet Skies Coalition, which has chapters in nearly two dozen states.

Last year, the 50 members of Congress who sit on the Congressional Quiet Skies Caucus thought they’d achieved meaningful change when they succeeded in getting specific noise-control requirements in the Federal Aviation Administration Reauuthorization Act of 2018, which was signed into law in October 2018. Sadly, the FAA doesn’t appear to be taking congress very seriously, as most communities near major U.S. airports have still not gotten any relief.

What’s insightful about the article above is that Congresswoman Speier is pressing for further changes—such as fines against airlines if they land planes during certain night-time hours. Few Americans know that there’s a global United Nations agency called the International Civil Aviation Organization, which is based in Montreal Canada. ICAO has regulatory authority over such matters as how much money can be levied as fines for noisy operation. This tactic used at the local level could help communities get the quieter conditions they yearn for, and the sleep they need.

If nothing else, fining airlines for noisy aircraft could stimulate those airlines to do what 50 airlines around the world have already done: purchase quieter aircraft–such as the 70% quieter Airbus A320neo when equipped with the American-made Pratt & Whitney “Geared Turbofan” engine.

We have no financial ties to airlines or aircraft manufacturers, but it seems essential to us for Americans to realize that quieter jet aircraft exist and are already flying safely around the world—but that only a couple of U.S. airlines have bought them. Why? Don’t we deserve quieter airports here in America too? Why do America’s airlines continue to buy noisy aircraft when quieter and more fuel-efficient alternatives already exist?
