戏曲学员嗓音与性激素变化的观察

Observation on Changes in Chinese Local Opera Students,Voice and Sex Hormones

对９２名１２～１９岁的男女戏曲学员用放射免疫法和声谱分析法，分别于１９９３年３月和１９９４年６月进行了两次血清睾酮（Ｔ）、雌二醇（Ｅ_２）和嗓音基频、音域的检测和比较。结果发现：最高音频男、女各年龄组皆上升，女性最为明显；最低音频女性逐年上升，男性各年龄组皆显著下降；男女的音域皆逐年增宽，但１７岁后男女音域变量值则互相接近。不论男女，Ｔ和嗓音基频呈负相关，而Ｅ_２和嗓音基频则呈正相关，但前者表现更为明显。

The techniques of radioimmunoassay and sound spectrum were used to test and compare the sero-testosterone(T),sero-estradiol(E_2) and the voice fundamental frequenies of 92 Chinese local opera girl and boy;students(12～19 years old) in March 1993 and June 1994,and found that:The highest frequency increased in the various female and rnale age-groups,but remarkably in female.The lowest frequency increased with each passing year in female,while it decreased abviously in the various male age-groups.The vioce frequency band widened remarkably with each passing year in all the age-groups.But after the age of 17,both variables for the voice frequency bend of female and male approximately equalled to each atter,For either female or male,the T formed a negetive correlate to voice fundamental frequncies,while the E2 and voice fundamental frequencies formed a reverse relation,but the former displayed obviously than the latter.
