Wind Instruments Categorized by COVID-19 Risk in New Study
A recent study by the University of Minnesota has categorized wind instruments into different risk levels for COVID-19 transmission based on aerosol concentration. The research, published in the Journal of Aerosol Science, aims to help musicians safely return to live performances.
The study found that certain instruments pose higher risks than others. Trumpets, oboes, and bass trombones were classified as 'high risk', emitting the most aerosols among the tested instruments. These players produced more aerosols while playing than even while speaking or breathing. On the other hand, the bass clarinet and tuba were deemed 'lower risk'.
The bassoon, piccolo, flute, bass clarinet, and French horn fell into the 'intermediate risk' category. Researchers attributed the tuba's lower risk to its longer tube length. Mouthpiece designs were also found to influence aerosol production.
To mitigate risks, researchers recommended social distancing, wearing masks over instruments, and using portable filters. None of the examined instruments spread aerosols further than one foot, but the type of instrument and playing technique can significantly impact aerosol production. This study provides valuable insights for musicians and orchestras looking to safely resume live performances.
