Abstract
Choral singing has become a major risk during the coronavirus disease 2019 (COVID-19) pandemic due to high infection rates. Our visualization and velocimetry results reveal that the majority of droplets expelled during singing follow the ambient airflow pattern. These results point toward the possibility of COVID-19 spread by small airborne droplets during singing.
摘要
在2019冠状病毒病（COVID-19）大流行期间，由于感染率高，合唱已成为一项重大风险。我们的可视化和测速结果显示，唱歌时呼出的大多数飞沫遵循周围气流模式。这些结果表明，唱歌过程中COVID-19有可能通过空气中的小飞沫传播。
