ABSTRACT:
The disclosure is directed to a vent adapter for an ear tip coupling for use with a modular "In The Ear" hearing aid. The ear tip has a bulbous distal tip portion with a sound delivering aperture and a plurality of vent apertures therein. In the assembly, the sound aperture of the ear tip is connected to a sound tube which is part of an adapter which seals the upper portion of the tip. The sound tube projects through the adapter and a separate vent tube also projects through the adapter to provide venting from the other apertures through the ear tip coupler and the vent tube. The vented ear tip and vent adapter can be formed in a number of alternative configurations for varying situations.
