This paper represents the exposure-response relationships for noise-induced hearing loss, metrics of noise exposure represent better the risk of hearing damage. In particular, while equivalent sound pressure level Leq, based on a 3dB exchange rate (ER) is used by most agencies, USOSHA's standard is based on the Lavg, which uses a 5 dB ER. In addition, peak levels of exposure, which are commonly found in some industries, including electrical site are believed to increase risk above that predicted by the Leq. This paper presents an analysis of noise matrix exposures parameters among electrical...
