ABSTRACT:
A processor controlled ear responsive hearing aid for the ear of a hearing impaired individual and method for operating a hearing aid. The input from the microphone is amplified and split into a plurality of band-pass channels each having a frequency range of approximately one-third octave. Each channel has an amplifier that is controlled by the processor. The processor receives control signals from a feedback microphone located in the ear canal and uses the control signals to develop a spectrum of the actual sound pressure levels by frequency at the eardrum. The processor compares averages of the actual sound pressure levels to the desired levels for each channel and for the overall output according to a predetermined set of instructions and controls the channel amplifiers and an output amplifier to produce the desired sound pressure levels for each frequency in the ear canal.
