Abstract: TITLE: NOISE REDUCTION SYSTEM            INVENTOR: WILLIAM A. COLE              ABSTRACT OF THE DISCLOSURE           Electronic   circuitry   as   described   which enhances the intelligibility of a speech signal corrupted by low-frequency noise while tending to retain frequency components  of  the  signal  characteristic  of  natural-sounding  speech.   The circuitry includes a broad band channel which passes the speech signal with little spec-tral distortion.   A high-pass channel produces a high-pass signal corresponding to high-frequency components of the speech signal, components which in themselves provide the human ear with considerable information for discern-ment of different sounds.  An operational amplifier in a summing configuration combines the broadband and high-pass signals to produce a processed speech signal with enhanced intelligibility.   Gain control circuitry asso-ciated with the high-pass channel reduces gain in the high-pass  channel  with  increasing  intensity  of  high-frequency  speech  signal  components  thereby  tending  to enhance the speech signal to an increasing degree at low signal levels and to otherwise produce a processed speech signal  suitable  for  reproduction  of  natural-sounding speech.
