Abstract
The acousto-mechanical properties of the skin and soft tissue in the ear canal and surrounding the ear play an important role in the attenuation of hearing protectors. In this report, the mechanical properties of skin are reviewed, and the morphology of the ear canal discussed. A technique of measuring the shear mechanical impedance of the skin in the ear canal is developed, and measurements taken on 20 adults. It is found that the relevant properties of the skin can be represented by a resistive and a compliant element. There are no significant differences found between older and younger subjects, or between males and females in the sample population tested. New formulations for artificial skin were developed, and a new module for the Acoustic Test Fixture (ATF) was designed, constructed, and tested.
