People do not realize how far singing distributes aerosols.
Here’s an interesting study on this:
Aerosol emission and superemission during human speech increase with voice loudness
“Early work by Papineni and Rosenthal16 and Loudon and Roberts19 reported that speaking (as exemplified by counting aloud) releases about 2–10 times as many total particles as a single cough. Similarly, Loudon and Roberts investigated the role of singing in the spread of tuberculosis and showed that the percentage of airborne droplet nuclei generated by singing is 6 times more than that emitted during normal talking and approximately equivalent to that released by coughing27. More recent work using advanced particle characterization techniques have yielded similar results21,28,29,30.”

Interesting info on the singing aerosols.
Makes sense, though, with the (lung) force required.
I wish there were more publicity on this. Loud talking and orating and singing on the subway were, to me, totally irresponsible. No one can shut up in this city.
When I got off the cars to wait for the next train, some people followed me, but they said things like “What was he doing? Spitting?”
I think common sense was one of the first victims.
All this nonsense about singing various songs while washing hands needs to stop :)
