The researchers estimated that one minute of ‘loud speaking’ can disperse 1,000 droplets containing virus particles into the air. The researchers decided that these droplets that had been unfold into the air might keep suspended within the air for greater than eight minutes. Theses particles might then be inhaled by these in shut proximity and, in response to the researchers, are “eminently capable of transmitting disease in confined spaces.” 1
