First Claim
Patent Images
1. A hearing aid comprising:
- a microphone for changing an acoustic input into an electrical signal;
a digital signal processor for analyzing and adjusting the electrical signal; and
a receiver which used the electrical signal output of the digital signal processor to produce a modified acoustic output;
wherein the digital signal processor comprises a switch for changing at least one parameter setting of the digital signal processor, the switch being controlled by an algorithm which analyzes the electrical signal for a signature hand motion of the user.

Abstract
A hearing aid switch utilizes pressure/sound clues from a filtered input signal to enable actuation initiated by a user by a signature hand movement relative to a wearer'"'"'s ear. The preferred signature hand movement involves patting on the ear meatus at least one time to generate a compression wave commonly thought of as a soft “clap” or “pop”. A digital signal processor analyzes the signal looking for a negative pulse, a positive pulse, and dissipation of the hand generated signal.

12. A method of switching at least one parameter setting of a digital signal processor of a hearing aid, comprising:
-
placing a hearing aid relative to the ear of a wearer, the hearing aid comprising; a microphone for changing an acoustic input into an electrical signal; a digital signal processor for analyzing and adjusting the electrical signal; and a receiver which used the electrical signal output of the digital signal processor to produce a modified acoustic output; performing a signature hand motion relative to the ear with the hearing aid, the signature hand motion comprising contacting the ear meatus with the user'"'"'s hand. - View Dependent Claims (13, 14, 15, 16)

17. A method of switching at least one parameter setting of a digital signal processor of a hearing aid, comprising:
-
analyzing an electrical signal within the digital signal processor, the electrical signal being representative of at least some portion of sound received by a microphone of the hearing aid; identifying a signal portion producible by signature hand motion relative to the ear with the hearing aid, the identified signal portion having at least a positive pressure pulse having an amplitude beyond a positive pressure pulse threshold and a negative pressure pulse having an amplitude beyond a negative pressure pulse threshold, and a dissipation region after both the positive pressure pulse and the negative pressure pulse wherein the identified signal portion is significantly less than the positive pressure pulse and the negative pressure pulse; and upon identification of the signal portion, switching at least one parameter setting of the digital signal processor of the hearing aid. - View Dependent Claims (18, 19, 20, 21)
