摘　　要：目的探索儿童真耳-耦合腔差值(real-ear-to-coupler difference,RECD)的变化规律,与西方儿童标准值进行对比,为国内儿童RECD标准值的建立提供基础。方法120例儿童按测试年龄划分为8组,3~月龄组(组1)11例,6~月龄组(组2)15例,12~月龄组(组3)10例,18~月龄组(组4)10例,24~月龄组(组5)18例,36~月龄组(组6)18例,48~月龄组(组7)18例,60~83月龄组(组8)20例。分别对各组进行各频率双耳RECD测试,并与基于西方儿童标准值进行对比,分析其变化规律。结果本组儿童总体RECD平均值低于西方儿童标准值;3~6与7~11月龄,18~23与24~35月龄RECD值无显著差异;RECD总体上随着儿童年龄的增长逐渐减小;儿童左右耳间的RECD值无统计学差异。结论助听器验配时应尽量测得儿童个体RECD值,难以配合完成双耳测试的儿童可将一侧耳数值用于双耳。Objective To investigate the variation pattern of real-ear-to-coupler difference(RECD)in children,and to compare it with the standard values of Western children.Thus,to provide a basis for the establishment of the standard values of RECD in children in China.Methods A total of 120 children participated in this study,and were divided into 8 groups according to the test age.Binaural RECD tests were performed for each group at each frequency.The standard values established for Western children were compared,and their variation patterns were analyzed.Results The mean values of RECD in Chinese children were generally lower than the standard values of RECD in Western children.There were no significant differences in RECD values between 3~6 and 7~11 months of age,and between 18~23 and 24~35 months of age.RECD values decreased gradually with the age of children.There were no statistical differences in RECD values between the right and left ears of children.Conclusion Individual RECD values should be measured during hearing aid fitting.In addition,one ear value can be used for both ears for children who have difficulty in completing binaural testing.
