Acoustics. Hearing protectors - Subjective method for the measurement of sound attenuation Ingestion-build-58320 which helps you in determiningWhat is this standard about? This document specifies a subjective method for measuring sound attenuation of hearing protectors at the threshold of hearing. The method is a laboratory method designed to yield reproducible values under controlled measurement conditions. The values reflect the attenuating characteristics of the hearing protector only to the extent that users wear the device in the same manner as did the test subjects. For a more
