Initial findings in a study of aerosol rates and accumulation from wind instruments and voice have been released, providing preliminary guidance on returning to in-person rehearsals while mitigating the risks associated with COVID-19. The research is being conducted at the University of Colorado and the University of Maryland and is commissioned by an international coalition of performing arts organizations including the League of American Orchestras. While the findings have yet to be validated, the results so far explore aerosol flow and emissions for the clarinet, oboe, flute, trumpet, horn, low brass, and voice; provide measurements for different mitigation techniques; provide initial modeling of COVID-19 particle concentrations in indoor and outdoor scenarios; and offer general considerations for safer rehearsal practices. The research team cautions that these preliminary results have not yet been tested or peer reviewed; final results will be available in December. Learn more here.
