Investigation of physical and psychophysical methods for the attenuation measurement of circumaural hearing protectors with implication for field use
… measures for assessing a hearing protector's effectiveness were evaluated through comparison to the standardized real-ear attenuation at threshold (REAT) method, termed 1I3-REAT, a psychophysical procedure (ANSI S3.19-1984). One alternative deviated from the standardized procedure primarily …
