对１００名正常成人及１２３名喉病患者嗓音进行了定量检测，测试了周期变异系数、频率微扰商，振幅微扰商，频率变动幅度、相对于平均微扰、谐噪比六个声学参数。结果显示：正常成人六个参数年龄组及性别组间差异无显著性；病态嗓音谐噪比低于正常，差异有显著性，其余参数高于正常，有统计学差异。提示：声学参数对嗓音优劣有客观定量评价作用，是喉科辅助诊断的客观定量指标。
The voices of 100 normal adults and 123 laryngeal patients were quantitatively tested. The parameters of the periodic variation coefficient, frequency perturbation quotient, amplitude perturbation quotient, frequency variation range, relative to average perturbation, harmonic ratio of six acoustic parameters . The results showed that there was no significant difference between the six age groups and sex groups in normal adults. The morbidity and the noise ratio of pathological voice were lower than normal, the difference was significant. The rest parameters were higher than normal and statistically significant. Tip: Acoustic parameters of the merits of an objective quantitative assessment of the role of voice, laryngology is an objective and quantitative diagnostic indicators.
