| 摘 要： | 通过对３６例正常人和３０例病态嗓音者的频域相对信噪比进行分析，结果表明，正常女性嗓音的频域相对信噪比呈稳定分布，而病态嗓音的相对信噪比，１７００Ｈｚ频段，与正常人比较，有显著差异，可以认为频域相对信噪比及区分病态嗓音和正常嗓音的有效参数。

| Abstract: | The frequency-domain relative harmonics-to-noise ratios were analysed in 36 normal women and 30 patients who had suffered from abnormal voice. The result indicated: the frequency-domain relative harmonics-to-noise ratios of the normal voice were distributed stably and the relative harmonics-to-noise ratios of the diseased voice differed obviously from that of the normal one above 1,700 Hz (P < 0.01). The frequency-domain relative harmonics-to-noise ratio was considered as a valuable parameter in distinguishing normal voice and diseased voice. |
