Fig. 1From: An audio attention computational model based on information entropy of two channels and exponential moving averageAn illustration of the audio attention processing. The signal waveform marked in red has three-stage signal that represents three attention events triggered by some environment factors, and the begin of three events marked in green can immediately cause high value of attention, but this process will gradually decrease. on the other hand, the intervals between some events can also attract us a period of time, the change in attention values marked in blueBack to article page
