| Abstract: |
Progress in hearing aids has come a long way. Yet despite such progress hearing aids are not the perfect answer to many hearing problems. Some adult ears cannot accommodate tightly fitting hearing aids. Mouth movements such as chewing, talking, and athletic or other active endeavors also lead to loosely fitting ear molds. It is well accepted that loosely fitting hearing aids are the cause of feedback noise. Since feedback noise is the most common complaint of hearing aid wearers it has been the subject of various patents. Herein a hearing aid assembly is provided eliminating feedback noise. The assembly includes the combination of a hearing aid with a headset developed to constrict feedback noise.

1. A hearing aid assembly eliminating feedback noise, the assembly comprising a hearing aid in combination with a feedback constricting headset, the hearing aid including a microphone, an amplifier, and a speaker in a case adapted to be worn behind an ear, and an ear mold adapted to fit in an ear to carry amplified sound to an eardrum, the feedback constricting headset including a compress, a pressure plate, and a headband, the compress being a soft compressible pad, sized to cover the ear concha to obstruct incoming external noise, and shaped to press, when depressed, on the ear mold, the pressure plate being a thin disk, sufficiently rigid to depress the compress, the headband being a resilient band shaped to fit a head, and adapted to hold the pressure plate over the compress with the band resiliency urging the pressure plate inwardly to depress the compress against the ear mold with a force required to hold the ear mold in place.
