FIELD: acoustic equipment. SUBSTANCE: method involves converting input voice signal into frequency spectrum, detection of filter characteristics using first value provided by ratio of frequency spectrum to evaluated level of noise spectrum which is present in frequency spectrum, and second value which is provided by maximal ratio of cycle level of signal of frequency spectrum to evaluated noise level and evaluated noise level. Noise in input voice signal is rejected using filtering corresponding to filter characteristics. Another claim of invention discloses device for noise suppression. EFFECT: increased efficiency of noise suppression. 5 cl, 10 dwg |
