声门闭合不良4种发声方式频率与正常人对比分析

目的 :了解声门闭合不良 4种发声方式 (最低音、舒适音、真声最高音和假声最高音 )和不同发音持续最大时间 (最大声时 )的频率变化参数。方法 :用 2 0 3 1型频谱分析仪检测 15 0例功能性声门闭合不良患者 4种发声方式的频率 ,并与正常男女各 3 0例作对比。结果 :从整体看 ,男女最低音的频率 ,闭合不良者明显高于正常人 ,假声最高音的频率则前者明显低于正常人 ;按最大声时不同与正常人比 ,总的趋势是随着最大声时延长 ,最低音和舒适音的频率下降 ,真声和假声最高音的频率上升 ,且有的组间对比差异显著。结论 :声门闭合不良患者发低音和高音的功能同时下降 ;其低音与高音功能随最大声时的延长而增强

A contrast analysis of four phonation methods frequency between patients with glottis closure disturbance and normal human

Objective:To find out frequency change parameters of four phonation methods (minimum,natural,maximum and falsetto maximum voices) and different maximum phonation persistent time (MPPT) of them in patients with glottis closure disturbance (GCD).Method:With frequency spectrum analysis,the frequencies of four phonation methods were studied in functional GCD patients (150 cases) and normal human (60 cases).Result:There were marked differences of voice frequencies between them not only in male but also in 5 female.And with the prolongation of MPPT,the voice frequencies also changed.Conclusion:The functions of both low and high voices decline in GCD patients.With the prolongation of MPPT,the functions of low and high voices strengthen in GCD patients.
