Abstract
Spectators are exposed to a variety of loud noises at air shows, which can contribute to noise-induced hearing loss. A previous study [Pääkkönen et al., Appl. Acoust. 64, 121–127 (2003)] on three Finnish air shows concluded that their air shows did not seem to exceed damage risk levels. This study investigated noise that spectators are exposed to at the Warriors Over the Wasatch Air and Space show at Hill Air Force Base. Noise dosage, exposure times, and LAeq for various aircraft were analyzed. The LAeq ranged from 75 to 95 dBA and the total noise dosage for the airshow was 118 %, exceeding the NIOSH recommended exposure limits with most of the noise coming from the fighter jets. This shows that spectators should use hearing protection if they plan to stay for the entire air show or at least during portions of an air show that contain fighter jets.
