The airborne lifetime of small speech droplets and their potential importance to SARS-CoV-2 transmission

Valentyn Stadnytskyi; Philip Anfinrud; Christina E. Bax; Adriaan Bax

 Movies that show the experimental setup and the full 85-minute observation of speech droplet nuclei.

 

The full movie recording of highly sensitive laser light scattering observations that indicate loud-speaking generates, in addition to hundreds of regular droplets, also many thousands of micro-droplets per second. This movie clip shows the decay of airborne particles.

 

Note: some parts of the audio of the clips were muted for privacy.
