Abstract:
    The invention is concerned with management system for volume. Read an output simulation audio frequency signal and transform it into a figure audio frequency signal. Sampling the figure audio frequency signal gets some swing values in a scheduled time. Count the cumulated value of audio frequency energy in the scheduled time, according to the some swing values. When the cumulated value is arriving at a scheduled value, send an order signal. In order to answer the signal, output a reminding sound to remind user to reduce current volume control value. This invention offers a management method of volume. The system and method reduce the current volume control value to keep the audition of user, when the cumulated value of audio frequency energy is arriving at a scheduled value.
