Abstract
Abstract A hearing aid to be worn behind the ear of a user includes a microphone. An earphone is also provided. The microphone and earphone are electrically connected by a signal path. An electronic setting circuit is provided in the signal path for electrically setting at least one transmission parameter in the signal path. The electronic setting circuit is controlled by a switch of the hearing aid. A signal output device is also provided, and is controlled by the switch. The signal output device provides information to the user regarding the transmission parameter selected. The signal output device outputs at least one signal that is characteristic of every electronically set transmission parameter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A hearing aid for an impaired user comprising: a microphone; an earphone connected to said microphone via a signal path; at least one electronic setting means, electrically connected to said microphone and to said earphone, for setting a transmission parameter in said signal path between said microphone and said earphone; signal output means, electrically connected to said at least one electronic setting means and to said earphone, said signal output means including an audio frequency generator, for transmitting a signal to said earphone having an audio frequency generated by said audio frequency generator for causing said earphone to emit a tone which uniquely identifies the transmission parameter which has been set by said at least one electronic setting means; and switch means, electrically connected to said at least one electronic setting means and connected via said at least one electronic setting means to said signal output means, for selectively activating said at least one electronic setting means and said signal output means.
Claim 2
Dependent Claim
162 words
A hearing aid for an impaired user comprising: a microphone; an earphone connected to said microphone via a signal path; at least one electronic setting means, electrically connected to said microphone and to said earphone, for setting a transmission parameter in said signal path between said microphone and said earphone; signal output means, electrically connected to said at least one electronic setting means and to said earphone, said signal output means including an audio frequency generator, for transmitting a signal to said earphone having an audio frequency generated by said audio frequency generator for causing said earphone to emit a tone which uniquely identifies the transmission parameter which has been set by said at least one electronic setting means; and switch means, electrically connected to said at least one electronic setting means and connected via said at least one electronic setting means to said signal output means, for selectively activating said at least one electronic setting means and said signal output means.
Claim 3
Dependent Claim
15 words
A hearing aid as claimed in claim 1, wherein said switch means is automatically actuated.
Claim 4
Dependent Claim
29 words
A hearing aid as claimed in claim 2, wherein said transmission parameter is preprogrammed, and wherein said transmission parameter is selectable based on a sound environment of said user.
Claim 5
Dependent Claim
51 words
A hearing aid as claimed in claim 1, further comprising a reset circuit connected to said at least one electronic setting means, wherein said reset circuit is electrically activated by at least one of faulty operation of said switch means and actuation of an on/off switch provided on said hearing aid.
Claim 6
Dependent Claim
65 words
A hearing aid as claimed in claim 1, further comprising a counter circuit connected via said at least one electronic setting means to said switch means and via said at least one electronic setting means to said signal output means, said counter circuit counting output signals from said switch means and controlling said signal output means based on a counter reading of said counter circuit.
Claim 7
Dependent Claim
20 words
A hearing aid as claimed in claim 1, wherein said signal output means is further defined by a voice generator.
Claim 8
Dependent Claim
44 words
A hearing aid as claimed in claim 1, wherein said switch means is further defined by a manually actuatable switch, said hearing aid further comprising a timer circuit connected via said setting means to said manually actuatable switch for controlling said manually actuatable switch.
