Exhalation Emission Simulator

Respiratory System Similation Systems that mimic human or other animal exhalation events are disclosed. Exhalation events that can be reproduced include coughing, sneezing, breathing, talking, gagging, panting, and singing. Air flow and airway systems cooperate to eject a gas cloud comprising the at least some air produced from the air flow system and one or more of a plurality of droplets, solid residues, or aerosols. The exhalation emission systems can be used in testing emissions in various environments, medical, and protective equipment usage situations. Methods related to the same are also disclosed.
