Abstract
Certain types of hearing aids are designed to be worn completely in the ear. Examples of such hearing aids include in-the-ear (ITE), in-the-canal (ITC), completely-in-the-canal (CIC) type, or invisible-in-the-canal (IIC) hearing aids. Described herein are structures to help prevent wax accumulation in the sound port that conveys sound to the microphone. In one embodiment, an injection molded T-fitting connects to a microphone and provides both a microphone inlet pathway and a wax relief pathway.
