Sumary of Making musical performances safer in the era of COVID-19:
- The researchers examined the extent and velocity of air jets, or plumes, coming from singers’ and actors’ mouths and from wind instruments, such as the flute, clarinet, trumpet and saxophone.
- They also measured airborne respiratory particles, or aerosols, and carbon dioxide levels emanating from the performers.
- They found that aerosol concentrations coming from the bell of a clarinet were comparable to singing.
- Placing a surgical mask over a singer’s face or over the clarinet bell substantially reduced plume velocities and lengths and decreased aerosol concentrations in front of the masks.
