“…All subjects were also part of a previously-published study analyzing singers’ masks, measured on the same day. 11 There were no voice complaints by any of the subjects and their Voice Handicap Index showed no vocal impairments. Further, respiratory problems were excluded by medical history and spirometry (ZAN, Inspire Healthcare, Oberthulba, Germany).…”

“…8 , 32 , 33 To not trigger convectional flows, the subjects were standing still on the same marked point on the stage during inhalation and exhalation. Similar to previous studies, 9 , 10 , 11 , 12 , 18 , 34 the study was conducted in a Bavarian Television Broadcasting Studio with the dimensions of 27 m x 22 m x 9 m. Three synchronized high-definition Sony television cameras (Sony, Tokyo, Japan, resolution 1920 × 1080 pixels, 25fps) recorded the tasks from a side view (C1), a front view (C2), and a top view (C3). Before and after all tasks and each subject the hall was aerated via opposing doors opened for a minimum of 2 minutes.…”

“…As a consequence, safety concepts, such as distancing, singers’ masks, room aeration systems, plexiglass walls, etc have been invented and evaluated, in order to assess and reduce the transmission risks as much as possible and to make musical gatherings, ie, lessons, rehearsals, and performances, possible and safe. 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 …”

IntroductionGroup musical activities using wind instruments have been restricted during the CoVID19 pandemic due to suspected higher risk of virus transmission. It was presumed that the aerosols exhaled through the tubes while playing would be ejected over larger distances and spread into the room due to jet stream effects. In particular, the soprano recorder is widely used as instrument in school classes and for beginners of all age groups in their musical education, as well as in contexts of leisure activities and in professional concert performances.Understanding the aerosol impulse dispersion characteristics of playing the soprano recorder could assist with the establishment of concepts for safe music-making.MethodsFive adult professionally trained soprano recorder players (4 female, 1 male) played four bars of the main theme of L. van Beethoven’s “Ode to Joy” in low and in high octaves, as well as with 3 different potential protection devices in the high octave. For comparison they spoke the corresponding text by F. Schiller. Before each task, they inhaled .5 L of vapor from an e-cigarette filled with base liquid. The vapor cloud escaping during speaking or playing was recorded by cameras and its spread was measured as a function of time in the three spatial dimensions. The potential safety devices were rated in practicability with a questionnaire, and their influence on the sound was compared, generating a long-term average spectrum from the audio data.ResultsWhen playing in the high octave, at the end of the task the clouds showed a median distance of 1.06 m to the front and .57 m diameter laterally (maxima: x: 1.35 m and y: .97 m). It was found that the clouds’ expansion values in playing the recorder with and without safety measures are mostly lower when compared to the ordinary, raised speaking voice of the same subjects.The safety devices which covered the instrument did not show clear advantages and were rated as unpractical by the subjects. The most effective reduction of the cloud was reached when playing into a suction funnel.ConclusionThe aerosol dispersion characteristics of soprano recorders seem comparable to clarinets. The tested safety devices which covered holes of the instrument did not show clear benefits.
