声带振动波形分析方法的研究

Study on analysis method of vocal fold vibration graph

目的 :利用声带振动波形图诊断嗓音疾病 ,避免人眼主观误差得出准确的结论。方法 :参照电声门图的研究方法 ,利用16个特征点 ,运用数学分析 ,建立声带振动波形图分析方法及量化分析公式。结果 :提出了声带振动波形图所特有的声带双侧振动对称性研究方法及公式。结论

Objective: To avoid the subjective error from the naked-eye when a laryngological diagnose is made by applying vocal fold vibration graph.Methods: Refering to the method of electronic glottis graph and mathematics analysis, using 16 characteristic dots, an analysis method and quantitative analysis formula are established.Results: A study method and formula of the left-right symmetries of vocal fold vibration which is peculiar to larynxphotokymography are established.Conclusion: This analysis method is an effective method for laryngological diagnosis by use of larynxphotokymography.
