Abstract: Objective To explore the real ear to coupler difference (RECD) changes in children with hearing aids .Methods 132 severe to profound hearing impaired children who came to hearing center for hearing aids exami-nation and adjustment were recruited into the study .They were put into 6 groups according to the test age ,<1 yr group(15 cases) ,1 yrs group(26 cases) ,2 yrs group(36 cases) ,3 yrs group(29 cases) and 4 yrs group(26 cases) . And all of them had the RECD tests for both ears with custom earmolds .Results The average RECDs for both ears decreased with the age increased .There were statistically differences for the same lateral ears when age differences surpass 2 years except for the difference for left ears between the children in the <1 yr group and 2 yrs group .This study showed there were statistically differences between left and right ears for majority of groups (except for 2 yrs group) .Conclusion RECD is an important factor for individual adjustment .The current results show that the chil-dren with hearing aids should have RECD tests for both ears at least once per two years .
