Abstract A hearing aid device which comprises a venting tube adapter for connecting the sound tube from the hearing aid amplifier to the molded ear insert and at the same time venting the channel to the auditory canal of the ear to which the hearing aid is connected. The adapter is made of plastic and it is provided with a part that extends into a hole through the ear insert so that the channel through this hole and through the adapter is connected to both the sound tube from the hearing aid amplifier and to the auditory canal of the wearer''s ear. In addition, the plastic adapter is provided with a venting hole that is controlled by a small adjustable screw which is threaded into the adapter and which is prevented from being accidentally removed therefrom by means of a plastic flange surrounding the shank of the screw and formed with the plastic of the adapter.
In a hearing aid apparatus, a venting adapter for connecting the round tube from a hearing aid amplifier to an ear mold, comprising: a first hollow tubular body member having a hole therethrough, said tubular member having one end adapted for attachment of the sound tube leading from a hearing aid and said tubular member having the hole at the other end threaded; a second hollow tubular member having one end fixed to said first tubular member and having a hole therethrough communicating with the first tubular member hole and having the other end adapted for attachment to an ear mold such that sound transmitted from the sound tube of the hearing aid will pass through said tubular member holes to the ear mold and on to the ear auditory canal of the hearing aid wearer; a vent opening in said first tubular member near the other end thereof and leading from the hole therein to the outside of the tubular member at a point external to the ear; and a threaded screw member threaded into the threaded hole at the other end of the first tubular member such that by turning the threaded screw member it will be caused to overlap and regulate the size of the vent opening for regulation of the volume of sound transmitted through the adapter to the ear auditory canal of the wearer.
