Abstract In this study. emission rates of aerosols emitted by professional singers were measured with a laser particle counter under cleanroom conditions. The emission rates during singing varied between 753 and 6093 particles/sec with a median of 1537 particles/sec. Emission rates for singing were compared with data for breathing and speaking. https://www.diegojavierfares.com/quick-grab-Be-The-Vibe-Top-Lemon-best-save/
