Impulse Dispersion of Aerosols during Singing and Speaking: A Potential COVID-19 Transmission Pathway

Echternach et al discuss their study on impulse dispersion of aerosols during singing and speaking as a potential COVID-19 transmission pathway. Group singing events have been associated with several outbreaks of infection during the coronavirus disease (COVID-19) pandemic. This link supports the possibility that aerosols are partly responsible for person-to-person infection. The study aims to analyze the impulse dispersion dynamics of aerosols in professional singers concerning the differences between singing a text, singing a vowel, or speaking at different levels of loudness.
