Summary

In this study, the aerosols emitted during various respiratory activities will be quantified in healthy subjects. The differences in aerosol size spectrum and number during tidal breathing, speaking, coughing and singing will be assessed. Subjects with an endogenously high aerosol emission will repeat the respiratory activities wearing face masks with varying particle filter capacity to investigate the aerosol emission reduction.
