News Release 7-Sep-2020
Lund University
If silence is golden, speech is silver - and singing the worst.
Singing doesn't need to be silenced, however, but at the moment the wisest thing is to sing with social distancing in place. The advice comes from aerosol researchers at Lund University in Sweden. They have studied the amount of particles we actually emit when we sing - and by extension - if we contribute to the increased spread of Covid-19 by singing.

The study shows that singing - particularly loud and consonant-rich singing - spreads a lot of aerosol particles and droplets into the surrounding air.
"Some droplets are so large that they only move a few decimetres from the mouth before they fall, whereas others are smaller and may continue to hover for minutes. In particular, the enunciation of consonants releases very large droplets and the letters B and P stand out as the biggest aerosol spreaders", says Malin Alsved, doctoral student of Aerosol Technology at Lund University.
