On urban noise

February 2

We open February with an article share. The article is about noise in urban areas. Not surprisingly, most noise comes from transportation and the solutions mentioned in the article not only addresses transportation noise but at the same time addresses other concerns about transportation, including safety.

Durand-Wood, E. (January 25, 2024) "Why Are Cities So Noisy? And Can We Do Anything About It?" Strong Towns, https://www.strongtowns.org/journal/2024/1/25/why-are-cities-so-noisy-and-can-we-do-anything-about-it [Last accessed: 2/2/2024]

To quote from the article:

"In 2011, the WHO set recommendations for daytime and nighttime environmental noise levels, and found the maximum safe noise level for daytime is 55db (somewhere between moderate rain and normal conversation) and at night, 40db (about the level of a quiet library). Beyond these levels, prolonged exposure to environmental noise has been shown to cause health problems, and not just hearing-related ones."In 2011, the WHO set recommendations for daytime and nighttime environmental noise levels, and found the maximum safe noise level for daytime is 55db (somewhere between moderate rain and normal conversation) and at night, 40db (about the level of a quiet library). Beyond these levels, prolonged exposure to environmental noise has been shown to cause health problems, and not just hearing-related ones.

Until recently, most analysis related to urban noise has focused on noise as an annoyance or disruptor to humans. But with these new guidelines, there was an acknowledgement that too much environmental noise can actually have grave health consequences, noting that "at least one million healthy life years are lost every year from traffic-related noise in the western part of Europe."

We now know that higher levels of environmental noise raise heart rate and blood pressure, cause harmful sleep interruptions, and are linked to cardiovascular disease, dementia, and cognitive impairment in children, among others. And as with environmental pollution, there are racial and socioeconomic disparities with noise pollution.

In a 2022 report, the United Nations identified urban noise pollution as a top environmental risk."

Have you noticed how noisy it is in our cities? Many actually choose to live in the suburbs as the perception is its quieter especially during the night. The health risks due to noise are well-established as presented also in the article. However, there are ways to address this and reduce the noise, particularly the type attributed to transportation and traffic.
