摘要 应用微型计算机和北京邮电大学通用信号谱分析系统分别对168例中轻程度喉病患者和87例同年龄健康人的嗓音信号进行分析,结论是频率微扰商是检测声带本体层病变的有效参数,但却不能有效地检测声带覆盖层病变. The computer and USSA were used to analyse voice signals of 168 patients with moderate or light degrees of laryngeal disease as well as 87 contrast normal adults. It is indicated that the Frequency Perturbation Quotient is an efficacious parameter in detecting the laryngeal disease in the vocal cord's body, but not in the vocal cord's cover.
