Here's my favourite record of a 'natural experiment' (Derryberry et al., Science 2020) due to the changes in the acoustical environment produced by COVID (air) traffic measures. I have occasionally used it in teaching:

Californian songbirds adapting the acoustics of their songs (level, spectrum, complexity) to the dramatically changed soundscapes!

In teaching research methods to music-psychology students, for years I have illustrated a "natural experiment" by discussing how shutting down air traffic in the aftermath of 9/11 allowed climate scientists to determine the effect of aircraft vapor trails on earth's overall temperature. (Do vapor trails cool the earth by blocking sunlight, or is the net effect to warm the earth by blocking reflected surface heat from radiating into space?)

I'd like to have an updated example, preferably something we learned about music or hearing arising from Covid isolation -- something students could better relate to.

Any suggestions?

Cheers,

David Huron
