Abstract

A head simulator, for testing respirators, has a head simulator body (2) with a simulated oral aperture (6) and with a simulated oral cavity (4), which is located behind the simulated oral aperture (6) in the head simulator body. A loudspeaker (8) is arranged in the simulated oral cavity (4). An audio unit (20) is connected to the loudspeaker (8) for reproducing speech via the loudspeaker (8). The head simulator includes a simulated trachea (10), which is in connection with the simulated oral cavity (4) and opens into the simulated oral aperture (6). An air delivery device (30) is provided, which can be operated to allow air to flow through the simulated trachea (10) and the simulated oral aperture (6).
