Aerosol emission of child voices during speaking, singing and shouting	2020-09-18		.txt	text/plain	2974	181	61	This is also due to the fact, that there has been no reliable data available on aerosol emissions from children's speaking, singing, and shouting. By utilizing a laser particle counter in cleanroom conditions we show, that children emit fewer aerosols during singing than what has been known so far for adults. Due to the principles of voice production and the described accumulation of SARS-CoV-2-infections during choir rehearsals (Hamner et al., 2020) , it is assumed that singing is connected with increased aerosol emission rates. The present study confirms higher emission rates of aerosols for singing in comparison to speaking also for children. On the contrary, in the shouting condition, which is not related to limitations in the child's singing technique, some children reached higher emission rates than adults during loud singing. In the first task, the emission rates for three different vocal test conditions were compared: (a) speaking, (b) singing, and (c) shouting.	./cache/cord-104078-o89bzjfi.txt	./txt/cord-104078-o89bzjfi.txt
