Noise and the increased risk of serious stroke

This report in Science Daily describes a fascinating study done in Barcelona. The study found that patients who lived in noisy areas suffered worse strokes than those who didn’t. Patients who lived in quieter areas near green zones, on the other hand, had less severe strokes.

Only this report and the abstract, published in Environmental Research, are available outside a pay wall, so I can’t comment on the scientific methods used in the study, but Environmental Research is a well regarded, peer-reviewed scientific journal. And the study results are consistent with past experience.

Hypertension is a well-known risk factor for stroke, with higher blood pressures being associated with more severe strokes. The Barcelona report supports other studies, including human, animal, and epidemiology studies, showing that noise exposure increases blood pressure due to autonomic nervous system and hormonal stress responses to noise. I suspect that is the likely explanation for the new study’s findings.

Dr. Daniel Fink is a leading noise activist based in the Los Angeles area. He is the founding chair of The Quiet Coalition, an organization of science, health, and legal professionals concerned about the impacts of noise on health, environment, learning, productivity, and quality of life in America. Dr Fink also is the interim chair of Quiet Communities’ Health Advisory Council, and he served on the board of the American Tinnitus Association from 2015-2018.

Using “thick data” to make a smart city

Adrian Smith, The Guardian, writes about Barcelona, a “pioneering Smart City,” that has been using sensors in various city infrastructure along with citizens via mobile devices “to monitor and anticipate urban phenomena in new ways, and, so the argument goes, efficiently manage urban activity for the benefit of ‘smart citizens.’”

Enter the residents living around Plaça de Sol, a popular square that has become, for residents, a bit too popular, especially with bars, restaurants, hotels, and tourists.  And with the addition of more bars, restaurants, and tourists, comes more noise, always. So back in 2017, a group of technology activists got in touch with residents and started a project under which residents were given “tools to measure noise levels, compare them with officially permissible levels,” with the aim of reducing noise in the square.

And what followed shows how complicated the embrace of thick data and citizen engagement can be, as the residents’ desire to reduce noise has to be considered along with the needs of bar and restaurant owners.  As a city councilman pointed out:

Beyond economic issues are questions of rights to public space, young peoples’ needs to socialise, neighbouring squares worried about displaced activity, the Council’s vision for Gràcia, and of course, the residents suffering the noise.

Barcelona is taking back city streets from cars

and giving them back to the people. Why? To make them more pedestrian friendly, boosting local businesses and reducing air and noise pollution. Vox has created a short 5-minute video explaining the concept and showing how Barcelona is going to start implementing its new Urban Mobility Plan. One hopes that U.S. city planners are following this development very closely.
