Researchers from the University of Michigan have found that daily average sound levels were down almost three decibels when the lockdowns started in March. That's, of course, compared to pre-new normal months January and February.

"The analysis demonstrates the utility of everyday use of digital devices in evaluating daily behaviors and exposures."
According to the study, the decibel drop was initially seen on weekends. But, this was also observed on weekdays, too, as lockdowns became more stringent. The researchers looked at data from 5,894 Apple Watch and iPhone owners.
