Abstract: A programming apparatus combination for programming an auditory prosthesis comprises a computer system and a portable programming device. The computer system comprises a general purpose operating system, a user interface for accepting auditory prosthesis programming information from a user, and a communications interface for communicating the programming information from the personal computer.

Abstract: A hearing aid is set forth that includes one or more hearing aid components that introduce an undesired undamped peak into the frequency response of the hearing aid. An electronic damping filter is utilized to compensate for the undamped peak. The electronic damping filter has a notch filter response that includes an inverse peak across the frequency range of the undamped peak thereby electronically damping the frequency response so that the hearing aid output is generally unaffected by the undesired characteristics of the inverse peak.The electronic damping filter may be programmable to vary the magnitude and/or shift the frequency of the inverse peak. A method is set forth that exploits this programmability and allows the same circuit topology to be used in two different hearing aids respectively having two different undamped peaks. A further method allows handling two or more peaks.

Abstract: Apparatus and method for reducing the interference of digital cellular telephones with hearing aids. A digital cellular phone is provided with a second antenna that transmits a local, low-power signal which fills in the gaps in the transmitted switched information carrier. This prevents the hearing aid from demodulating the low frequency switched carrier components of the digital cellular phone. Alternatively, the main antenna can transmit on a garbage frequency between time slots, or the hearing aid can detect and cancel the interfering signal.
