Droplets that propagate via the laser beam scatter light, which is recorded with a cell phone digicam. A easy laptop algorithm is used to rely the droplets within the video. The experimental setup is easy and may easily be built and operated by nonexperts. There could also be some non-health care work settings the place medical masks may be more appropriate than non-medical masks. This is as a result of they allow infectious respiratory particles to unfold outside the mask. These masks donotprotect others from COVID-19 or restrict the unfold of the virus.

The purple horizontal line in E and F indicates a threshold P value of zero.1.

3A, the place we show the relative droplet depend for every examined masks. For this speaker’s management trial, the absolute droplet count was about 960. A graph with a corresponding logarithmic scale could be present in fig. The extra speakers’ reference counts for the control trial had been about 200, with comparable fractional variance to the main speaker (see fig. S2 for particulars).
