Abstract:
Objective To investigate the variation pattern of real-ear-to-coupler difference(RECD)in chil-dren,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 Indi-vidual 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.
