OBJECTIVE
The purpose of the study was to investigate the effects of age and gender on adolescents' vocal tract dimensional development with acoustic reflection technology (ART).
METHODS
A total of ninety-five male and female adolescents aged between 10 and 18 divided into three age groups were tested with acoustic reflection technology (ART) and acoustic program to secure their vocal tract dimensional parameters and the vowel formant frequencies.
RESULTS
Significant age and gender effects were found not only in vocal tract length, but also segmental volumetric measurements, as well as the vowel formant frequencies.
CONCLUSIONS
The findings of this study have provided insights on the developmental trend of adolescents' vocal tracts. The study has also offered a preliminary anatomical database of adolescents' vocal tract dimensional growth for otolaryngologists, clinical anatomists, speech therapists and other health professionals of swallowing, respiration and communicative disorders.
目的
本研究旨在利用声反射技术（ART）探究年龄和性别对青少年声道尺寸发育的影响。
方法
共有95名年龄在10至18岁之间的青少年（分为三个年龄组）接受了声反射技术（ART）和声程序测试，以获取他们的声道尺寸参数和元音共振峰频率。
结果
研究发现，年龄和性别不仅对声道长度有显著影响，对节段容积测量以及元音共振峰频率也有显著影响。
结论
本研究结果为青少年声道的发育趋势提供了见解。该研究还为耳鼻喉科医生、临床解剖学家、言语治疗师以及其他吞咽、呼吸和交流障碍方面的健康专业人员提供了青少年声道尺寸生长的初步解剖学数据库。
