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 potentiometer retention mechanism is provided for mounting a potentiometer on the faceplate of a hearing aid. The potentiometer includes a rotatable knob attached to a housing with the housing including a plurality of conductive leads projecting from a back surface of the housing. The mechanism includes an adapter for receiving the potentiometer. The adapter has a device for mechanically engaging the faceplate such that the adapter is secured with the faceplate. The mechanism further includes a plurality of angled leads attached to the adapter whereby the potentiometer leads press against the angled leads such that the housing is secured within the adapter.
