Abstract
A method of processing speech before it encounters high noise levels near the listener is described. The system, composed of a high-pass filter followed by an amplitude normalizer, results in intelligibility more than twice that of normal speech at a signal-to-noise ratio of -2.5 dB (re 0.0002 dynes/cm2). Intelligibility enchancement is shown for a range of signal-to-noise ratios from -10 dB to +10dB.
