Abstract

In the context of the high risk of airborne transmission of COVID-19, the question of the production of particles while playing wind instruments is highly relevant. Therefore, in this study, 23 professional musicians played their instruments in a cleanroom in cleanroom-grade clothing. The most common orchestral wind instruments flute, oboe, clarinet, and trumpet were therefore chosen. Aerosol measurements using a laser particle counter were conducted to quantify the emission rate of respiratory particles. Orchestral excerpts as well as sustained tones in two dynamic levels were played. The emitted particles were mostly in a submicron size range. For all instruments besides the clarinet, an influence of the loudness of playing on the emission rate could be observed. The emission rates for all musical instruments were independent of the passages played. Flute and oboe showed similar emission rates but lower than the values for clarinet and trumpet. While playing a note with a small volume, the flute, oboe, and trumpet have a similar emission rate as found for speaking.

音乐家演奏管乐器、木管乐器和铜管乐器时的粒子发射率调查

由于 COVID-19 在空气中传播的风险很高，因此在演奏管乐器时产生微粒的问题非常重要。因此，在这项研究中，23 位专业音乐家穿着洁净室级别的服装在洁净室中演奏了他们的乐器。因此，选择了最常见的管弦乐器长笛、双簧管、单簧管和小号。使用激光粒子计数器对气溶胶进行测量，以量化呼吸道粒子的排放率。测量过程中演奏了管弦乐选段以及两种动态水平的持续音调。发射出的微粒大多为亚微米级。除单簧管外，所有乐器的发射率都受演奏音量的影响。所有乐器的发射率都与演奏的段落无关。长笛和双簧管的发射率相似，但低于单簧管和小号的发射率。在演奏小音量的音符时，长笛、双簧管和小号的发射率与说话时的发射率相似。

期刊介绍： The quality of the environment within buildings is a topic of major importance for public health. Indoor Air provides a location for reporting original research results in the broad area defined by the indoor environment of non-industrial buildings. An international journal with multidisciplinary content, Indoor Air publishes papers reflecting the broad categories of interest in this field: health effects; thermal comfort; monitoring and modelling; source characterization; ventilation and other environmental control techniques. The research results present the basic information to allow designers, building owners, and operators to provide a healthy and comfortable environment for building occupants, as well as giving medical practitioners information on how to deal with illnesses related to the indoor environment.
