In rescue and air medical transport operations, the exposure of crew and patients to sound pressure and vibration levels differs from the exposure of a crew on air taxi or private flights. This difference is caused primarily by the different flight configurations required in operations and also by the large variation in exposures during a working day, as there are days with many operations and others with none. Flight patterns and aircraft types directly influence the sound pressure and vibration levels to which crews and patients are exposed. This research project aims to investigate the vibroacoustic conditions inside aircraft that are used by the security forces of the State of Santa Catarina during rescue and air medical transport missions.
