Your Guide To Masks
Droplets that propagate via the laser beam scatter mild, which is recorded with a cellphone digicam. A easy laptop algorithm is used to depend the droplets in the video. The experimental setup is easy and can simply be built and operated by nonexperts. There may be some non-well being care work settings the place medical masks could also be extra acceptable than non-medical masks.

3A, the place we show the relative droplet count for every examined masks. For this speaker’s control trial, the absolute droplet rely was about 960. A graph with a corresponding logarithmic scale could be present in fig. The extra audio system’ reference counts for the control trial have been about 200, with related fractional variance to the principle speaker (see fig. S2 for details).
