Filed:

Feb 2, 2005

Appl. No.:

11/049495

Inventors:

David Holmes - Colleyville TX, US

International Classification:

H04R 25/00

US Classification:

381330000, 181129000, 381328000

Abstract:

A hearing aid eartip coupler system and method is disclosed which permits interfacing existing hearing aids with a variety of high performance hearing aid eartips for use by patients with mild to moderate hearing loss. Conventional hearing aid earmolds connected to over-the-ear hearing aids suffer from a high degree of feedback and “tunnel effect” associated with blockage of the ear canal by the earmold, as well as unsightly large eartip tubes. The present invention permits cost-effective over-the-ear hearing aids to be retrofitted with a variety of vented hearing aid eartips and smaller eartip tubes to improve the performance and appearance of the overall hearing aid system for use with patients having mild to moderate hearing loss. Additionally, the use of the disclosed coupler system and method permits replacement and/or resizing of the hearing aid eartip should this portion of the system be deemed unsuitable for use by the patient.

US Classification:

381330000

Abstract:

A hearing aid eartip is disclosed for use with an over-the-ear hearing aid which incorporates a means for accepting a detachable wax guard for the purposes of preventing wax buildup in the hearing aid sound transmission tube. The disclosed invention is effective at transmitting sound from an over-the-ear hearing aid to the patient's ear canal, is easily inserted into the patient's ear canal, and provides for a more aesthetically pleasing form factor than the prior art. The disclosed invention controls cerumen, improves overall hearing aid gain, and reduces unwanted hearing aid feedback.
