| 摘 要： | 为了了解中国幼儿外耳道声学共振特性的发育规律,并与欧美幼儿的数据作比较,藉以探讨欧美流行的小儿助听器处方选配公式是否可直接移植到中国幼儿身上,对45名学龄前幼儿,在真耳分析仪允许的声场条件下,测试儿童外耳道的声学共振特性。同步设置16名成人对照。结果表明中国成人与儿童的共振峰频率存在显著性差异;随年龄增长,小儿的外耳道共振峰频率移向低频(由4589Hz至3550Hz);中国儿童外耳道声学特性与欧美儿童不同,各年龄段的共振峰频率与欧美报道的结果均有显著性差异。应用国外开发的小儿助听器验配处方公式时,应采用儿童个体的真耳测量数据。

| Abstract: | The study investigate the developmental rule of external ear canal resonance characteristics in Chinese children and compare with western countries' data. The aim is to explore the possibility of application of DSL prescriptive formula in Chinese children, which is very popular formula on pediatric hearing aid fitting. 45 pre-school children's (from 3 to 7 of age) ear canal resonance characteristics, also as REURs, are measured by AuricalTM audio-diagnostic fitting system in sound-proof test room. Control group consisted of 16 adults. There are significant differences on ear canal resonance characteristics between Chinese adults and Chinese children. The average peak of REUR of children is moving forward to low frequency (from 4589 Hz to 3550 Hz) with the growth of age. The average peak frequency of ear canal resonance of Chinese children is significantly different from that of western children in all of age groups. The difference of ear canal resonance characteristics between children and western children suggests that we should facilitate individual real-ear measurement data when we are fitting hearing aid for Chinese children. |
