中老年正常人发音“i:”时呼气流量、声强、基频及其相互关系的研究

RESEARCH OF THE RESPIRATORY FLOW RATE,THE INTENSITY AND THE PITCH FREGUENCY OF “i:” VOCAL SUBJECTS OF MIDDLE AND OLD AGE

本文应用喉音气流仪对120名(40～69岁)男女进行了舒适平稳发“i:”音的检测。结论:1.初步确定了男女发“i:”音时呼气流量、声强、基频的正常范围,男女在基频上有显著差异;2.男女发“i:”音时基频的平均瞬时变化率在0.0～0.3%之间;3.确定了发音效率的评价方法;4.男女最长声时随年龄增长而缩短;5.提出了用呼气流量与肺活量之比评价唯功能的优劣。

Phonation functions were measured by phono -laryngograph in 120 normalpersons(40～69year)who were phonating 'i: 'vocal.The results were as following.The normal range of the respiratory flow rate,the intensity,the pitch frequencywere obtained in normal male and female, the pitch frequency had significantdifference in male and female (P<0.01). The average movement regulation ofthe pitch frequency ranged from 0.01% to 0.3% .The method for the estimationof the phonation efficiency was obtained. Maximum phonation time becameshorter when persons were older.The ratio of respiratory flow volume to vital capacity could be used to estimate the function of larynx.
