Zusammenfassung:	The present invention relates to a method for producing comfortable noise in back wave elimination process. Said method includes the following steps: obtaining absolute values of residual back wave amplitude and background noise amplitude; comparing the above-mentioned two absolute values; defining that when the absolute value of the described residual back wave amplitude is greater than the absolute value of the described background noise amplitude, utilizing amplitude-limiting treatment to make the amplitude of the described residual back wave be equal to the amplitude of the described background noise so as to generate comfortable noise.
