随着COVID-19疫情的发展，管乐器演奏期间空气传播感染的高风险日益受到关注。我们与明尼苏达管弦乐团的16位音乐家合作，采用多种实验和数值技术来量化现实表演条件下十种管乐器发出的气流和气溶胶浓度。对于所有仪器，流量和气溶胶影响区的范围限制为30 cm。更远的地方，人体产生的热羽流是主要的流动来源。气流和气溶胶浓度随音乐振幅、音高和音符持续时间的变化而变化，这取决于演奏技术和乐器的几何形状。用扬声器布覆盖喇叭铃并在乐器出口上方放置过滤器可以大大降低气溶胶浓度。我们的研究结果表明，通过适当的风险缓解策略，乐器表演可以在空气传播疾病的低风险下进行。
There has been growing concern about high risk of airborne infection during wind instrument performance as the COVID-19 pandemic evolves. In collaboration with 16 musicians from the Minnesota Orchestra, we employ multiple experimental and numerical techniques to quantify the airflow and aerosol concentration emitted from ten wind instruments under realistic performance conditions. For all instruments, the extent of the flow and aerosol influence zones are limited to 30 cm. Further away, the thermal plume generated by the human body is the dominant source of flow. Flow and aerosol concentration vary in response to changes in music amplitude, pitch, and note duration, depending on playing technique and instrument geometry. Covering the trumpet bell with speaker cloth and placing filters above the instrument outlet can substantially reduce the aerosol concentration. Our findings indicate that with appropriate risk mitigation strategies, musical instrument performance can be conducted with low risk of airborne disease transmission.
