Abstract : Problems arising from the presence of noise in air evacuation aircraft are described. These include effects of noise on understanding speech and the possibility of noise-induced hearing loss. Examples of noise spectrums found in current air evacuation aircraft are given and their implications discussed. The effectiveness of ear protective devices, plugs and muffs, is described and factors involved in successful earplug use are listed. (Author)
