Investigation of physical and psychophysical methods for the attenuation measurement of circumaural hearing protectors with implication for field use
A field-implementable measure is needed to estimate the attenuation workers are achieving with their hearing protectors in the field. Alternative measures for assessing a hearing protector's effectiveness were evaluated through comparison to the standardized real-ear attenuation at threshold (R...
