Abstract
A noise suppressor selects, for individual frequency components, maximums by comparing a plurality of noise suppressed spectraanda plurality of noise suppressing unitsandoutput, thereby obtaining an output spectrumhaving the frequency components selected as its components. A first noise suppressing unitgenerates a noise suppressed spectrumby multiplying an input spectrumby amplitude suppression gains, and makes the amplitude suppression gains greater than most of the amplitude suppression gains in a noise signal intervals of a second noise suppressing unit
