婴啼频谱分析与初步研究

The Frequency Spectrum Analysis and Primardy Study of the Infants'Cries

本文对６个月以下的２０例正常婴儿及４０多例有病婴儿的哭声录音进行了频谱分析与研究，结果表明，正常婴儿与有病婴儿的哭声频谱有明显区别；在哭声基频，三维动态频谱的形态，最高共振峰的频率等方面均有显著不同，从而得出有可能根据婴啼频谱分析区分正常婴儿及有病婴儿的结论．

The article has analysed and studied the spectrums of infant cry records which came from 20 normal infants ac 40 ill infants who are all younger than 6 months. Result shows that the cry spectrums of normal infants are obviously obviously different from those ones of ill infants.infants.In many aspects such as basic rrequency. the feature of three dimension dynamic spectrum.the frequency of the highest resonant peak,they are different.Therefore we conchuded that it is possible that we can distinguish the normal infanta from ill infants according to the cry spectrum analysis.
