Abstract

A number of significant hearing protectors' standards that have been implemented to encourage and protect healthy hearing are discussed. These standards are divided into three categories, such as measurement standards, applications standards, and combination of both standards. Measurement standards describe the method of measuring the sound attenuation at the threshold of hearing protectors. The attenuation is defined as the difference in sound levels that extract the threshold of hearing when the subject is protected and when he is not wearing the protector. The application standards use the results from the measured standards to calculate the noise level of the protected ear in dBA. The combination standard is intended to serve as guidance to manufacturers and users. It proposes two ways of calculating the noise level of the protected ear using two estimates.
