摘要
当16名正常受试者从最低音、中音、高音及假声发元音“i”时,对其环甲肌、甲杓肌做了肌电图检查。同时对20名音乐学院声乐系学生整个音域的频率、声强、声门下压力、气流率进行了测量。结果表明:随着发音频率的升高,环甲肌及甲杓肌的电活动逐渐增强。在最低音发音时环甲肌的电活动较小,没有甲杓肌强。在高音及假声发音时,环甲肌电活动最强。尤其在假声音域,环甲肌与甲杓肌共同协同作用来完成对频率的调节。当发音频率逐渐升高时,声强及声门下压力同样也逐渐升高,呈正相关(P<0.01)。频率与气流率也为正相关(P<0.01,除2个男低音之外)。有10名受试者在发高音和假声时,气流率的值呈现零值和负值。声门下压力及喉内肌的电活动在调节基频中起到了重要的作用,气流率在调节基频中也有一定的作用,但在发高音和假声时,有1/2的受试者的气流率几乎没有起作用,呈现零值或负值。
