目的：应用声反射技术（ART）研究年龄和性别对青少年声道尺寸发育的影响。方法：对95名年龄在10 ~ 18岁的青少年分为3个年龄组，采用声反射技术（ART）和声学程序对其声道尺寸参数和元音形成频率进行测试。结果：年龄和性别不仅对声道长度有显著的影响，而且对音段体积测量和元音形成峰频率也有显著的影响。结论：本研究结果对青少年声道发育趋势有一定的启示。该研究还为耳鼻喉科医生、临床解剖学家、语言治疗师和其他吞咽、呼吸和交流障碍的健康专业人士提供了青少年声道尺寸发育的初步解剖学数据库。2010爱思唯尔爱尔兰有限公司版权所有。
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.
