Abstract

A hearing aid includes at least one capacitive switch for controlling or communicating with the hearing aid by touch. The capacitive switch is an electrode on the inside of the housing coupled to a touch detector. Touching the outside of the hearing aid adjacent the electrode produces a switching operation. The hearing aid includes a programmed microprocessor coupled to the touch detector. The microprocessor is programmed to effect predetermined functions in response to particular touch patterns.

Claims

1. A hearing aid including a housing containing electronics for processing audio signals and other functions characterized in that:

the hearing aid further includes at least one capacitive switch coupled to said electronics for operating the hearing aid;

said electronics includes a touch detector coupled to said capacitive switch and a programmed microprocessor coupled to said touch detector; and

said microprocessor is programmed to effect predetermined functions in response to particular touch patterns.

2. The hearing aid as set forth in claim 1 wherein said microprocessor is programmed to turn audio processing on or off in response to a touch on the capacitive switch.

3. The hearing aid as set forth in claim 1 wherein the hearing aid includes more than one capacitive switch.
