Talking can also launch thousands of droplets so small they can remain suspended in the air for eight to 14 minutes, according to a new study. ExperimentsScientists agree that coronavirus jumps from person to person most often by hitching a ride inside tiny respiratory droplets. They may land on surfaces like doorknobs, where people can touch lingering virus particles and transfer them to their face. The laser scans showed that about 2,600 small droplets were produced per second while talking. When researchers projected the amount and size of droplets produced at different volumes based on previous studies, they found that speaking louder could generate larger droplets, as well as greater quantities of them.
