Clarinets and oboes, on the other hand, typically create an abundance of aerosols, but they are controllable.
“When you put a surgical mask over the bell of a clarinet or trumpet, it reduces the amount of aerosols back down to levels in a normal tone of voice,” Hertzberg said.
Similar risk reduction-efforts were evaluated by engineers at the University of Minnesota.
Led by mechanical engineering Ph.D. student Ruichen He, the team conducted an analysis of various instruments along with the flow field and aerosols they created. Rarely did the aerosols produced travel more than a foot away, despite the level created varying by instruments and musicians.
Their discovery led them to develop seating for live orchestras that took the pandemic into account. The seating model detailed where filters should be placed and audience members ought to be seated to lessen the risk.
Another study reviewed the risk of COVID-19 infection by traveling to and from the office via passenger cars.
Brown University engineering professor Kenny Breuer and his team conducted mathematical simulations of the way air moves through passenger car cabins to identify procedures that may lessen the risk of infection. They found that strategically opening some windows and closing others in a passenger car may decrease the risk of transmission if air enters and exits a room at a distance from passengers.
