<p>A noise suppressing method and an apparatus wherein a high quality of noise suppression can be achieved by use of a reduced amount of calculation. Input signals are converted to frequency domain signals, the bands of which are integrated to obtain integrated frequency domain signals. These integrated frequency domain signals are used to determine an estimated noise. This estimated noise and the integrated frequency domain signals are used to determine a suppression factor, which is then used to weight the frequency domain signals, thereby suppressing the noise included in the input signals.</p> |
