Abstract
Ventilation systems are often designed to meet air quality standards for gases inhaled by people confined within a limited space. An additional concern is how aerosols generated by talking, coughing, sneezing, etc. are distributed and cleared from that environment. This is especia1ly true far aerosols associated with the spread of communicable diseases. The object of this study was to design and develop a system to simultaneously measure human activity and the generation, distribution, and clearance of aerosols in a confined space. A system has been developed which provides a video record that is synchronized with the output of a matrix of aerosol .analyzers. The stored aerosol records can be post-processed to provide a three dimensional representation of particle concentrations within the confined space superimposed on the video record of human activity.
