正常老年人嗓音变化的观察与分析

目的：综合分析正常老年人嗓音变化的特征，方法：以喉声图仪采集权、分析１４６例正常老年人嗓音声样。结果：老年人嗓音基频下降，８０岁以上男性基频升高，老年期共振峰低频谐波规则，声能强，男女声之间差异减少，老年男性谐嗓比随增龄有下降趋势，而振幅微扰商则升高，老年女性以上参数变化不明显。结论：老年期嗓音变化属老年人正常生理变化。通过喉声图仪测得其嗓音参数的变化，可作为正常老年期嗓音的客观指标。以鉴别病理嗓

Observation and analyses on voice changes in the normal aged

Objective:To measure the voice samples of the normal aged in order to systemically study the features of the voice changes. Method:To collect and analyze 146 voice samples of the normal aged with sonogram. Result:The fundamental frequency of the voice of the aged decreases and rises in the male more than 80 years older. The low frequency harmonics are regulation and the intensity is strong in the formant of the aged. The difference reduces in voice between male and female. The harmonics to noise ratio tends downwards and the amplitude perturbation quotient tends upwards along with the growth of age in the aged male. The changes of the above-mentioned parameters are not significant in the aged female. Conclusion:The voice changes are normal physiological ones in the normal aged. The changes of the parameters are used to evaluate normal aged voice and abnormal one. The changes show that the function in the aged phonation tends to decline to a certain extent and it must be protected and be trained.
