Impulse noise hazard as a function of level and spectral distribution. Final report

Price, G R

Data are presented from a series of experiments on hearing loss from weapons impulses in which cat ears were exposed to weapons impulses and tested electrophysiologically. Hazard increases as the spectral peak moves upward from about 100 Hz (large caliber weapon) toward the mid-range (3.0 kHz.). These data are consistent with the content that there is a spectrally dependent critical level at which loss processes become reversible to only a limited degree and permanent changes in the ear result. Furthermore, none of the existing damage-risk criteria in use in the world assesses hazard in a manner consistent with these data.
