Abstract:
In a gain adjusting method and a gain adjusting device for adjusting gain of a processed voice signal that is obtained by signal processing of an input voice signal, a masking power of the processed voice signal is computed, and gain is adjusted for every frequency if the frequency is masked according to the masking power, such that a difference between the processed voice signal and the input voice signal where the frequency is not masked is canceled.
