Objectives: The aim of the study is to determine the effect of a cochlear implant on the ability to understand

speech in a noisy environment.

Materials and Methods: Turkish HINT was applied to the experimental group consisting of 15 children with a

unilateral Cochlear Implant (CI) aged between 7;9, and 13;9 (year; month) and the control group consisting of 15

children aged between 8;10 and 13;0 with normal hearing. Speech Reception Thresholds (SRTs) of the groups

were obtained in quiet and noise in front conditions. The data obtained from the groups were compared.

Results: The mean Speech Reception Threshold (SRT) in the quiet was found to be 65.4 dB in children with CI

and 21.6 dB in normal-hearing children. The mean SRT in noise was found to be +6.0 dB Signal to Noise Ratio

(SNR) in children with CI and -1.6 dB SNR in normal-hearing children. A significant difference was found

between the mean SRT values of the groups in quiet and noise conditions (p.0,01).

Conclusion: Children with CI need a higher SNR than children with normal hearing to understand speech in noise.

In addition, the age of children with normal hearing had a significant effect on speech understanding skills in noisy

conditions but not in quiet.
