Objective: The aim of this research is to analyse and compare the psychophysical tests in different age of patients with a cochlear implant. Method:One hundred and seventy patients with Nucleus CI24M cochlear implant system participated in this study. The patients were divided into four groups according to their age. They were group A (3 year), B(3-6 year), C(6-12 year) and D(12 year). The psychophysical tests included T and C-Level evaluation. Result:C-Levels of each electrode (except electrode No.20) were significantly different between group A and D at the time of one month after switch-on (P 0.01 , P 0.05 for the No. 2, 18, 19, 21, 22 electrode). The normalized differences between used C-Levels and C-Levels for group D were significantly higher than the other three groups at the switch-on session (P 0.01 ,P 0.05 between group D and C). The normalized differences between used C-Levels and C-Levels were significantly different for the group A and D at one week after first programming session (P 0.05 ). Conclusion:T and C-Level for different age groups were different. The normalized differences between used C-Levels and C-Levels were significantly different among the four groups in the few weeks after switch-on.
