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.

An insertable earpiece comprising, in combination: an elongated generally cylindrical hollow housing with a bulbous tip portion ventilated by a plurality of apertures in a distal end thereof and a flared proximal tip portion with an inner annular shoulder angled to the axis of said housing; a flanged adapter fitting seated against the inner annular shoulder of said housing to close the proximal end of said housing, said fitting including a sound tube projecting into said housing to communicate with at least one of said apertures in the distal end of said tip portion while more than one of the plurality of said apertures communicates with a chamber in said housing; and a vent tube projecting through said fitting into said chamber to provide a path from the auditory canal through said chamber to the outside, said vent tube portion extending into said housing being shorter than said sound tube and the other end of said vent tube being angled away from the axis of the tube delivering sound to said fitting.
