ABSTRACT:
A wax guard system, for use with an in-the-ear hearing aid, has a housing secured to the hearing aid shell and an insert which screws into the housing. The insert has a body having an internal passage therethrough, and a bridge extending across the exterior opening of the passage. The bridge is higher at its centre than at its ends and carries a thin domed disk which shields the opening and deters wax from entering the passage.
