Abstract
A larger external ear replica for use on a KEMAR manikin has been developed to meet the needs of hearing aid designers and other manikin users. The ear was selected from the 24 subject sample used by Burkhard and Sachs (1975) as the basis for the original ear development. Ear dimensions were chosen to be two standard deviations larger than the existing ear. A mirroring technique was used to give right and left ears with nearly identical properties. Responses of the manikin with the new ears are given and compared with responses with the original ears.
