The embodiment of the invention discloses a comfortable noise parameter generation method, compristing the following steps: calculating the energy eigenvalue and the frequency spectrum eigenvalue of each frame in a present group of successive frames; choosing one energy eigenvalue from the calculated energy eigenvalue of each frame as the energy parameter of the present comfortable noise to output; choosing a frequency spectrum eigenvalue from the calculated frequency spectrum eigenvalue of each frame and taking the cepstrum frequency parameter which is corresponding to the frame of the chosen frequency spectrum eigenvalue as frequency spectrum parameter of the present comfortable noise to output. Meanwhile, the embodiment of the invention also discloses a comfortable noise parameter generation device. By adopting the method and the device of the invention can generate the comfortable noise parameter easily and conveniently.
