Noise sensors are used in network-based digital broadcasting system, which are distributed in the field of each broadcasting area todetect the environmental noise of the broadcasting area in real tie and send the environmental noise of the broadcasting area to thecorresponding eauipment of the broadcasting system, the power amplifier automatically adiusts the broadcast volume of the corespond'ing broadcast area. When the instantaneous noise signal disappears, the data will also be sent to the corresponding equipment.
