正常成人嗓音频谱分析

Voice Spectrum Analysis in Normal Adults

为探讨不同性别及不同年龄阶段我国正常成人嗓音的声学特征,应用计算机频谱分析技术对145例18～80岁正常人的嗓音进行声学参数检测.结果表明:各年龄段男女基频(F_0),第二、三共振峰(F_2、F_3),频率微扰商(FPQ)以及中、青年男女间振幅微扰商(APQ)有显著性差异,男性振幅微扰商(APQ)随年龄增长而下降,六十岁以后又明显升高,老年男性基频(F_0)明显升高而老年女性基频(F_0)则明显下降.本研究可为临床嗓音的分析评估提供客观的方法和依据.

Acoustic parameters of 145 normal adults (18-80 years old) were measured with Universal Signal Spectrum Analysis System. The results showed that fundamental frequency (F0) ,the second and third formant (F2, F3 ) , frequency perturbation quotient (FPQ) between male and female in same age as well as amplitude perturbation quotient (APQ) between two sexes in young and middle age were statistically different. APQ reduced with the growing of age but increased obviously after 60 years old in male. F0 rose in old man but decreased significantly in old woman. The article indicated that voice had distinctive features in different sex or age, which could provide objective grounds for clinical voice evaluation.
