Accurate motor control is important, as different flow rates and aerosol volumes are used to reproduce various cough types. Comments Lindsley: “Simulating a cough involves replicating an intake of breath, closing the throat and building up pressure, followed by a sharp release of air from the lungs. The cough simulator is synchronized with a breathing simulator so that the cough initiates at the start of an inhalation cycle, with the resulting violent expulsion of air expelling aerosol particles in a detectable two-metre long airflow. After this, the particles spread as they are carried about a room by air currents.”
