Abstract
A hearing aid having hearing loss-compensating components, active occlusion reduction components, a vent, a tuned piston, and a flexible surround. The piston and the surround combination are assembled on the faceplate and cover the outside end of the vent that is situated on the faceplate. The piston and the surround combination minimize the adverse effects of walk-induced head vibrations.
Claims14
A hearing aid, comprising:
- an occlusion reduction system having a tuned resonator;
- a hearing aid housing having a rear end and a front end;
- a vent, extending from the rear end of the hearing aid housing to the front end of the hearing aid housing, said vent having a first end facing outside the ear and a second end facing the ear canal;
- and
- a tuned piston and a flexible surround combination covering said vent, the tuned piston and the flexible surround combination forming the tuned resonator.
2 more elements
A hearing aid, comprising:
- a. an external microphone that converts ambient sounds originating outside the ear into first representative electrical signals;
- b. an internal microphone that converts sounds originating inside the ear canal, including at least occlusion sounds, into second representative electrical signals;
- c. a signal processing system operatively coupled between the external microphone and the internal microphone that modifies and combines the first and second electrical signals to generate third representative electrical signals;
- d. a receiver that converts the third representative electrical signals into hearing-loss compensating sounds and occlusion-negating sounds and projects the hearing-loss compensating sounds and occlusion-negating sounds into the ear canal;
- e. a vent, extending from the rear of the hearing aid housing to the front of the hearing aid housing, having a first end facing outside the ear and a second end facing the ear canal;
- and
- f. a tuned piston and a flexible surround combination that is situated at the front of the hearing aid housing and that covers the first end of the vent.
