Acoustics - Hearing protectors - Part 2: Estimation of effective A-weighted sound pressure levels when hearing protectors are worn (ISO 4869-2:1994/Cor 1:2006); Corrigendum AC Withdrawn SN EN ISO 4869-2/AC:2007 Corrigendum from Publication date: Sep 2007 Version: Pages: 3 Language: English, French, German Services: Online, Online + Pdf

Abstract

The document describes 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 components. These methods are not suitable for use with peak sound pressure level measurements.
