Use of Cadaver Ears in the Acoustic Evaluation of Ear Plugs
Abstract
The attenuation provided by several types of ear plug in common use, and by an experimental amplitude-sensitive plug under development, was examined for both pure-tones and high level impulses using cadaver-ear techniques. The objective measurements with pure tones up to 110 dB are in fair agreement with those of conventional methods. The attenuation for impulses is shown to increase with peak pressure level in the case of the experimental plug, but to remain constant in that of the ordinary V.51R plug.
