ABSTRACT:
A hearing aid apparatus employs a single side band modulator which serves to convert an audio band of frequencies into an upper and lower side band signal. One of the side band signals is filtered and clipped. The clipped side band signal is then demodulated to provide an output audio signal relatively free of undesirable low frequency peaks. The output audio signal is then applied to a compressor amplifier circuit for application to the ear of a handicapped user.
