Acoustics. Hearing protectors - Estimation of effective A-weighted sound pressure levels when hearing protectors are worn Ingestion-build-98192 This Standard includes the followingWhat is this standard about? This document specifies three methods (the octave band, HML and SNR methods) of estimating the A weighted sound pressure levels effective when hearing protectors are worn. The methods are applicable to either the sound pressure level or the equivalent continuous sound pressure level of the noise. Although primarily intended for steady noise exposures, the methods are also applicable to noises containing impulsive
