Data from: Expiratory aerosol particle escape from surgical masks due to imperfect sealing

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.
