Verification of Flat Attenuation Characteristics of Musicians' Earplugs

Custom hearing protection devices that are designed to attenuate sound levels uniformly across a wide range of the audible frequency spectrum ("flat frequency attenuators," also known as Musicians Earplugs TM) are a common recommendation for hearing loss prevention programs for musicians. This presentation will describe the use of probe microphone measures to verify whether or not the attempt of "flat frequency attenuation" is achieved in the individual, and suggest a framework for interpreting verification measures.
