Abstract:

Noise-induced hearing loss NIHL is a major occupational hazard for military personnel. Although considerable evidence points to gender differences in susceptibility to NIHL, the precise nature of these differences, and how they apply to the types of noise characteristic of military settings is currently unknown. During Year 1, experiments were conducted with chinchillas to examine sex differences in a basic auditory sensitivity b susceptibility to temporary and permanent threshold shifts TTS and PTS, respectively caused by exposure to simulated Ml6 rifle fire c TTS and PTS caused by exposure to 0.5 kHz octave band noise and UH-60 Blackhawk helicopter noise and d the ability to benefit from prophylactic conditioning exposures. The results of these initial experiments point to sex differences in the response of the cochlea to noise, which could have important implications for military assigments and hearing conservation programs.
