Orchestral ensembles have faced many challenges when starting to perform again during the COVID pandemic, and contamination is a chief concern: specifically, whether wind instruments are vectors of contamination through aerosol dispersion. Researchers worked with musicians to deepen our understanding of how much aerosol is produced and dispersed by wind instruments. They used visualization to characterize the flow, tracked fog particles in the air, and measured aerosol concentration from wind instruments with a particle counter. Then they combined these to develop an equation to describe aerosol dispersion.
