    熵值越大则每个符号包含的平均信息量越大。有研究发现,在有噪声的语音信号中,语音信号的熵和噪声信号的熵存在着较大的差异,对噪声信号来说在整个频带内分布相对平坦,熵值小,语音信号集中在某些特定频段内,熵值大。因此利用这个差异可以区分噪音段和语音段。(The greater the entropy is, the greater the average information of each symbol is. It is found that, in noisy speech signals, the entropy of speech signals and the entropy of noise signals are quite different. For noisy signals, the distribution is relatively flat in the whole frequency band, and the entropy value is small. The speech signal is concentrated in some specific frequency bands, and the entropy value is large. So the difference can be used to distinguish the noise segment and the speech segment.)
