| 摘要: |
| 检测对象为20岁~30岁的男女青年。中轻度声带覆盖层病态组:女30人,男31人;正常组:女36人,男38人。结果表明男女正常嗓音的频域相对信噪比均呈一个稳定的分布。而女性、男性病态嗓音的相对信噪比分别在大于1700Hz和1000Hz频段与正常对照组有显著的差异(P<0.01)。认为相对信噪比是区分中轻程度声带覆盖层病态噪音和正常嗓音的有效参数,协同监视病态嗓音的频率微扰商和振幅微扰商参数的异常可基本识别声带本体层和覆盖层两类疾病。 |

| Abstract: |
| The cases were divided into two groups:30 females, 31 males in the diseased group; 36 females and 38 males in the normal group; all cases age ranging from 20 to 30 years.The result indicated that the relative harmonics-to-noise ratios of the normal voice for both male and female have a stable distribution. The diseased groups (with moderate or light laryngeal disease in the vocal cord's cover) differed significantly from the normal groups above 1700 Hz for female (P>0.01), and above 1000 Hz for male (P>0.01). It suggests that the relative harmonics-to-noise ratio is an effective parameter in distinguishing the normal and the diseased voice. The diseases in the vocal cord's cover and body could be detected combining with the unusual Jitter and Shimmer of the diseased voice. |
