Rating of Hearing Protector Performance for Impulse Noise

Abstract

Concern has often been expressed that the performance of hearing protectors in steady noise say not apply to their performance in impulse noise. Our current studies, as well as other studies, support the fact that there is a large difference in performance. In all cases, the performance of a protector is much better for impulse noise than for continuous noise. For example, we are obtaining at least 20 dB of protection (NRR) of essentially zero. We believe that it is not the NRR procedure at fault; but the fact that, for impulse noise, A-weighting does not discriminate enough against low-frequency energy....
