Updating the methods for estimating adequacy of HP attenuation

Individual fit-test methods are a potential tool for education, training, and measuring/documentation of individual hearing protector attenuation ratings; however, more studies are required to support specific recommendations on the use of fit-test systems. The US Air Force representatives of the ANSI WG 11 request the allowance of the methods described in ANSI S12.68 for use in estimating the adequacy of hearing protector attenuation; the methods should be ordered for level of accuracy (highest to lowest): Octave Band Method, NRSG, NRSA and finally NRR.
