ABSTRACT:
A differential input hearing aid with a programmable frequency response provides the hard of hearing with the capability to listen to individual conversations in the midst of high ambient background noise, and to have the frequency response of the hearing aid tailored to the individual user by programming the desired response characteristics into the hearing aid by digital signals. The audio inputs of two microphones are applied to a subtractive circuit with the balance of the inputs being controllable. Digitally controlled band pass filters with selectable band and selectable level of amplification are provided.
