本文对沈阳地区150名12～17岁青少年的嗓音基频进行了频谱分析。结果表明:同一年龄组中女性基频高于男性,性别差异非常显著(P均<0.01)。基频与年龄成反比,但15岁男性组、16岁及17岁女性组基频反常性升高,可能与变声期喉内软组织受到迅速增大的喉软骨过度牵拉变薄有关。同时还提示:除变声旺盛期嗓音异常外,听觉上无嗓音异常的部分变声期青少年的基频也有变化。
In this paper, the frequency spectrum of 150 basic frequency of 12 to 17-year-olds in Shenyang was analyzed. The results showed that: in the same age group, the female’s fundamental frequency was higher than that of the male, the gender difference was very significant (all P <0.01). The fundamental frequency is inversely proportional to age. However, the abnormal increase of the fundamental frequency of the 15-year-old male, 16-year-old and 17-year-old women may be related to the excessive stretching and thinning of the laryngeal cartilage which is rapidly increased in the larynx. At the same time also prompts: In addition to vocal exuberant voice abnormalities, the auditory abnormal voiceless part of the voice of teenagers also have changes in the fundamental frequency.
