A device for adjusting the frequency response of a hearing aid is provided. The device includes a module capable of being releasably secured substantially within the opening of the hearing aid such that the hearing aid is capable of remaining in the user's ear during programming. A mechanism for delivering electrical current and frequency response adjusting signals from a programming station to the device is connected to the device. The device further includes a mechanism for delivering electrical current from the module to the hearing aid thereby providing power to the hearing aid and a mechanism for delivering frequency response adjusting signals from the module to the hearing aid thereby allowing the frequency response of the hearing aid to be adjusted.

Frequency response adjusting device

A hearing aid faceplate assembly includes a faceplate having a volume control/switch receiving aperture. A volume control/switch integrated circuit assembly is mounted within the aperture. The volume control/switch integrated circuit assembly includes a module substrate, an amplifier mounted to the substrate and a volume control mounted to the substrate and electrically coupled to the amplifier.
