Ear Wax Barrier For A Hearing Aid

US Patent:
4870689, Sep 26, 1989
Filed:
Mar 31, 1988
Appl. No.:
7/170023
Inventors:
Erwin W. Weiss - Northbrook IL
Assignee:
Beltone Electronics Corporation - Chicago IL
International Classification:
H04R 2502
A61F 1102
US Classification:
381 686
Abstract:
An ear wax barrier for a hearing aid to prevent ear wax from contacting and damaging the internal components of a hearing aid or hearing aid receiver. The barrier includes a housing defining a central axis of passage, as well as a plurality of projections and a variable acoustic attenuator. The projections extend inwardly from the interior surface of the housing, each projection partially occluding the cross-sectional area of the housing. The projection provides a tortuous path for ear wax migrating into the hearing aid. The variable acoustic attenuator and the projections provide a constricted passageway for damping of the acoustic response of the hearing aid.

Ear Wax Barrier And Acoustic Attenuator For A Hearing Aid

US Patent:
4972488, Nov 20, 1990
Filed:
Jun 12, 1989
Appl. No.:
7/365083
Inventors:
Erwin M. Weiss - Northbrook IL
Mark F. Stanton - Mundelein IL
Assignee:
Beltone Electronics Corporation - Chicago IL
International Classification:
H04R 2502
US Classification:
381 686
Abstract:
A barrier for a hearing aid that combines the feature of both (1) preventing ear wax from contacting and damaging the internal components of a hearing aid or hearing aid receiver and (2) variably dampening the acoustic response of the hearing aid. The barrier includes, in combination, a housing defining a central axis of passage, as well as a plurality of projections and a screen. The projections extend inwardly from the interior surface of the housing, each projection partially occluding the cross-sectional area of the housing. The projections provide a tortuous path for ear wax migrating into the hearing aid, and the screen provides additional area for wax accumulation. The projections and screen also dampen or otherwise modify the frequency response of the hearing aid. The screen may also be interchanged or adjusted to accommodate the specific frequency attenuation needs of a particular user.
