Summary: 
This paper proposes a method which notifies deterioration in the sound data of the audience in advance for reducing their unpleasantness. The effects of the method are clarified by subjective evaluations. The experimental evaluation showed that the use of the Light Alarm, which changes colors form green to red for showing the degradation, is an effective way to present the degradation information in advance.
