Abstract:

Limits for exposure to hazardous agents are set by defining some specific acceptable effect the response and then determining what exposure conditions the dose produce that effect. In 1968, the Committee on Hearing, Bioacoustics, and Biomechanics CHABA proposed a limit for exposure to impulse noise gunfire in which the response was a specific amount of temporary threshold shift TTS and dose was specified in terms of the peak pressure and two aspects of the duration of a particular impulse, with correction factors for number of impulses and for the angle of incidence on the ear. The proposal was basically an endorsement of one advanced by an Anglo-American team of investigators Coles, Garinther, Hodge, and Rice, 1968 that was based on the very limited pool of information then available about the auditory hazard of gunfire. Coles, Garinther, and Hodge were members of the Working Group on Proposed Damage-Risk Criterion for Impulse Noise Gunfire.
