Effects of Spoken Phones and Patient Characteristics on Respiratory Aerosol Emission
Understanding respiratory aerosol generation, in different situations and individuals, is critical for advancing knowledge of airborne transmission of diseases. Our findings corroborate prior evidence of an association between SPL and particle emission in voiced activities. Particle production also varies systematically across different phones, irrespective of SPL. The predominance of small particles in the phonation of [r] suggests the production of satellite particles from the tongue vibration. The higher particle generation in the phonation of [o] compared with [a] suggests the oral opening may contribute to the number of emitted particles. None of the individual characteristics-age, sex, BMI, or PEF-was a systematic predictor of particle production across all respiratory activities.
