Abstract

The dataset provided here is associated with the work "Expiratory aerosol particle escape from surgical masks due to imperfect sealing," by Cappa et al, currently available as a preprint at https://doi.org/10.21203/rs.3.rs-142138/v1. This includes measurements made of the influence of surgical masks and leakage flows out the mask sides on the emission of micron-scale aerosols from various expiratory activities (coughing, speaking). The dataset provided here includes *.txt files exported from an Aerodynamic Particle Sizer that contain time-series of the abundance of particles, by size (in particles per second), measured in the breath of study participants across experiments wherein people were either talking or coughing. Also, *.txt files of the measured amplitude of the speech or coughing associated with these activities are provided. Data are provided for conditions when people were not wearing any masks or were wearing surgical masks. For wearing of surgical masks, data are provided for participants speaking or coughing while in various physical orientations with respect to the sampling instrument. Further details, including the file naming scheme, are provided in the associated Read Me file and the Usage Notes. All personally identifying information has been removed.
