Abstract

A hollow shell-type hearing aid is prepared from an impression of the ear. A mold is formed from the impression. An opening is cut in the mold and the mold is filled through the opening with hardenable material. The hardenable material is allowed to cure until a hard shell of the material forms on the surface of the mold. The remaining hardenable material is poured out of the mold through the opening and the shell is then removed.
