Aerosol emission is increased in professional singing [pdf]Paper  abstract   bibtex   
In this study, emission rates of aerosols emitted during singing are presented for professional singers. The results, measured with a laser particle counter, are compared with published data for breathing and speaking. In the investigated cohort of eight volunteers, the particle source strengths during singing are between 753.4 and 6093.14 P/s. The growth rates between singing and speaking are between 3.98 and 99.54. The present study contributes to a more precise assessment of a possible spread of SARS-CoV-2-viruses during singing. It should support the efforts to improve the risk management, especially for choir singing.
