Provided are a noise suppressing method, a noise suppressing device and a computer program, which can suppress a low-range component with a small operation quantity and which can achieve a noise suppression of high quality. The noise, as superposed on a desired signal in an input signal, is suppressed by transforming the input signal into a frequency range signal, by correcting the amplitude of the frequency range signal to determine an amplitude-corrected signal, by determining an estimated noise with the amplitude-corrected signal, by determining a suppression coefficient with the estimated noise and the amplitude-corrected signal, and by weighting the amplitude-corrected signal with the suppression coefficient.
