The Institute of Medicine carried out a study mandated by Congress and sponsored
by the Department of Veterans Affairs to provide an assessment of several issues
related to noise-induced hearing loss and tinnitus associated with service in the
Armed Forces since World War II.
The resulting book, Noise and Military Service: Implications for Hearing Loss and
Tinnitus, presents findings on the presence of hazardous noise in military settings,
levels of noise exposure necessary to cause hearing loss or tinnitus, risk factors for
noise-induced hearing loss and tinnitus, the timing of the effects of noise exposure
on hearing, and the adequacy of military hearing conservation programs and audiometric
testing. The book stresses the importance of conducting hearing tests (audiograms)
at the beginning and end of military service for all military personnel and
recommends several steps aimed at improving the military services' prevention of
and surveillance for hearing loss and tinnitus. The book also identifies research
needs, emphasizing topics specifically related to military service.
