Tellingly from the study, "It would appear that minimum contamination can best be achieved by not wearing a mask at al but operating in silence..." implies that the masks stop contamination when people are talking. Because ordinary people do talk, and talk a lot, is there anywhere a study specifically for Covid that compares a population of mask wearers with a population of non-maskers?
