[The application of frequency-domain harmonics-to-noise ratio in the acoustic analysis of the normal voice and the abnormal voice].
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.
