【摘要】：目的探讨不同年龄助听器佩戴儿童真耳耦合腔差值(real ear to coupler difference,RECD)变化趋势。方法将2010年6月至2012年5月在四川大学华西医院耳鼻咽喉头颈外科听力中心进行助听器检测调试的132例重度至极重度听力损失儿童根据测试时年龄分为1岁组(15例)、1岁组(26例)、2岁组(36例)、3岁组(29例)和4岁组(26例),各组分别进行双耳RECD测试并分析结果。结果随着年龄的增加,除1岁组与2岁组左耳外,不同年龄儿童同侧耳RECD均值呈减小的趋势,并且相差≥2岁时差异有统计学意义;除2岁组外,同年龄组左右耳的RECD平均值差异有统计学意义。结论 RECD有助于儿童助听器的个体化调试,一般每两年应至少进行一次RECD测试,并应双耳测试。
[Abstract]:Objective to investigate the real ear to coupler difference of children with different age hearing aids. RECD). Methods from June 2010 to May 2012, 132 children with severe to very severe hearing loss were examined and debugged by hearing aid in the ear, nose, throat, head and neck surgery hearing center of Huaxi hospital, Sichuan university. Divide the 1-year-old group according to the age at the time of the test (. 15 cases). Twenty-six patients (n = 26) and 26 cases (n = 26) in age group (n = 26) and group (n = 26) in age group (n = 36) and group of 4 years old (n = 26) were tested with binaural RECD and the results were analyzed with age. Except for the left ear of 1 year old group and 2 year old group, the mean value of RECD in the same lateral ear of children of different ages showed a decreasing trend, and the difference was statistically significant when the difference was more than 2 years old. There was significant difference in the mean value of RECD between the left and right ears in the same age group except for the 2-year-old group. Conclusion RECD is helpful to the individualized debugging of hearing aids in children. A RECD test should be performed at least once every two years, and a binaural test should be performed.

【正文快照】： 真耳耦合腔差值(real ear to coupler differ-ence,RECD)是指同一强度的测试声信号在人耳与2cc耦合腔内的强度差异,它有助于助听器验配人员更好对助听器进行个性化的调试,尤其是儿童,因为儿童不能像成人那样能够与验配人员进行互动交流,同时儿童和成人的外耳道有差异,不能简单
