Anfinrud et al. used laser gentle scattering to sensitively detect the emission of particles of various sizes whereas speaking. Aerosolized transmission dynamics are pathogen specific, as a result of pathogen-specific peak shedding and inactivation charges . Studies recommend that vibration of the vocal folds contributes extra to particle atomization and the manufacturing of particles that carry microorganisms .
