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.
In order to investigate the acoustic characteristics of normal adult voice in different genders and ages, the acoustic parameters of 145 normal adults aged 18 ~ 80 years were measured by computer spectrum analysis.The results showed that the basic frequency (F 0) The second, third formant (F_2, F_3), the frequency perturbation quotient (FPQ), and the amplitude of perturbation quotient (APQ) between men and women were significantly different. The amplitude of APQ decreased with age (P <0.05), and increased significantly after the age of 60. The study found that the basic frequency (F_0) of elderly men increased significantly while the basic frequency of elderly women (F_0) decreased significantly.This study may provide an objective method and basis for clinical voice analysis and evaluation.
