ABSTRACT:
Electronic circuitry for providing compensatory amplification to restore speech clarity for aurally handicapped persons comprising multiple active filters in a lowpass, bandpass, highpass (LP/BP/HP) configuration which provides composite filter responses applicable to infinite combinations of hearing deficiencies through multiple adjustments of filter gains, BP center frequency, LP/HP break frequencies, and BP filter "Q". This action achieves a precise corrective hearing response in wearable behind-the-ear and in-the-ear hearing aids.
