How ironic that a pandemic that devastated the health and well-being of millions of people worldwide resulted in an opportunity to conduct research to monitor the earth’s movements in ways that may provide information to protect the earth and its inhabitants from here on.

New research from the Royal Observatory of Belgium, the Imperial College London, and other institutions has found that dampening of seismic noise caused by humans, especially in more densely populated areas, has dropped by as much as 50% in some places, allowing researchers to listen in to “previously concealed earthquake signals.” The quiet time brought on by the pandemic was the longest time that “human-caused seismic noise” had been lessened since researchers had been monitoring the earth’s sounds. Now that researchers were able to tune in to the natural sounds of the earth, they believe the information provided by these sounds will enable them to gain a greater understanding of potential earthquakes and volcanoes.

To those of us who have advocated for less noise and greater quiet in our environment, largely based on the growing body of literature that has demonstrated the adverse impact of noise on mental and physical health, we welcome these new studies that provide us with another avenue of research to support our efforts.

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.

Noise abates as the pandemic rages on

This report from Yahoo! discusses work being done by the Royal Observatory of Belgium and the British Geological Survey that shows that people staying at home has made some measurable differences.

The work shows that low frequency noise created by humans, picked up by a network of seismometers, has decreased by 33%. The reduction in low frequency vibrations was confirmed by the British Geological Survey.

This new quiet may be one tiny silver lining in the scourge that is the COVID-19 pandemic.

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.
