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
OBJECTIVE: To understand the frequency change parameters of the four vocalizations (basso, comfort, real treble and falsetto) and the longest duration (loudest) of different vocal closures. Methods: Two hundred and thirty-one spectrum analyzers were used to detect the frequency of four sound patterns in 150 patients with functional glottis failure, and compared with 30 normal men and women. Results: As a whole, the frequencies of males and females were significantly higher than those of normal subjects, and the frequencies of the highest falsetto frequencies were significantly lower than those of normal subjects. When compared with normal subjects at the loudest time, the general trend was With the maximum sound duration extended, the frequencies of the bass and comfort sounds decreased, the frequencies of the treble of the real and falsetto increased, and there were significant differences between groups. Conclusions: The function of bass and treble in patients with glottic closure is reduced at the same time; the bass and treble functions are enhanced with the extension of the maximum vocal length
