An aerosol barrier system as an emerging technology for reducing airborne pathogens during singing

Abstract

Abstract In the initial stages of the COVID-19 pandemic, it became evident that singing carried a substantial risk of virus transmission. Consequently, new regulations were implemented to safeguard the population, and the adoption of singing masks emerged as a pivotal measure to curb the spread of COVID-19 during vocal performances. However, the discomfort and impediment to sensory expression caused by these masks posed significant challenges, particularly for individuals whose passions or professions revolved around singing. This study shows a novel solution to address these issues: the Aerosol Barrier System for Singing. The system features a transparent screen with an Impactor-Fan-Filter. The Impactor-Fan-Filter (IFF) is integrated into the transparent screen and strategically positioned within 1.5 feet of the singer's face. We demonstrated that the system effectively reduces the dispersion of aerosols generated during singing by over 99%. In addition, comparative sound analysis indicated that the system minimizes interference with sound waves, ensuring the preservation of sound quality. Furthermore, the transparent screen offers an unobstructed view of the singer, enhancing the overall performance experience. Our system adheres to several crucial criteria for an effective solution tailored to the needs of singers: it prioritizes safety and comfort, upholds sound quality, and facilitates an unrestricted view of the singer's entire face for the benefit of the audience, conductors, and ensemble members.
