Description
<p>To reduce the risk of droplet infection while enjoying entertainment events, a prototype droplet-suppression megaphone (DSM) was constructed from a single sheet of paper. We conducted droplet counting and visualization experiments with four sample patterns: no megaphone, normal megaphone, DSM1 (with one bending section), and DSM2 (with two bending sections). As a result, up to 250 droplets per frame were observed in the droplet-counting area of the sample without the megaphone immediately after the droplets were discharged, while the number of droplets was reduced to 1/5 in the case of the normal megaphone, at a frame rate of 30 frame/s. The number of droplets was further reduced to a maximum of 25 with the DSM1. The number of droplets in the DSM2 has not increased compared to the number of droplets in the background before droplet ejection.</p>
