发音共鸣腔的多导频谱同步分析

Synchronious Analysis of Multi-channel Spectrum for Human Resonance Cavity

应用多导频谱同步分析测试发音时共鸣规律、条件及特点。共测试１４０名，包括声乐工作者５０名，播音员２０名、声带疾患５０例，一般健康人２０名，采声样１０４０份，分别做位置（口、喉、头、胸）等方差分析。不同专业用声人员，不同声部及声带病变致音嘶之间的频谱分析有明显差异，提出了口、喉、头、胸各部部位的共鸣频率。头腔、口腔产生高频共振（２０００Ｈｚ以上——高共鸣腔），胸腔、喉腔产生低频共振（２０００Ｈｚ以下——低共鸣腔），提出了病理性音嘶临床分类。

he svnchronous analysis of multichannel spectrum were used to determine the regulars conditions and characters of the resonance when subjects pronounced.140 subjects were selected for test and 1040 pieces of sound sample were collected,then the analysis of different parts(mouth, throat,head and chest)was done. The results of the analysis of variance showed that there was much difference among the various professional workers, different places of articulation,and patients with voice disor- ders in spectrum analysis (P<0.001). Each part of resonance frequencies was put forward of pro- nouncing system. High frequency resonance comes from head and pharynx(above 2000 Hz high reso- nance cavity),and low,frequency resonance comes from chest and larynx(less than 2000 Hz resonance cavity).We suggest that there are six degrees of clinical objective classification of the pddathologic hoarseness.
