Cochlear implant is the only solution for bilateral profound sensorinural hearing loss there are two types of cochlear implant: single- and multi-channel.

Since innovation of multi-channel implant, using of single-channel implant has been decreased dramatically, and developed countries has stopped using it since 1989, but it still used in some developing countries.

This study aims to compare the performance of single- and multi-channel implant in terms of Auditory Performance and Speech Intelligibility.

This study was conducted on 16 child divided into two groups: the first group included 8 children with single channel cochlear implant (CI) and the second group included 8 children with multi-channel CI.

The average age in first group was 8 years and in second group was 7 years and two months.

In addition, The youngest child was 4 years, and the oldest was 11 years in both groups.

All children have been received aural rehabilitation for a period between 1-4 years and they were diagnosed with prelingual bilateral sensorineural hearing loss.

The auditory performance and speech intelligibility were evaluated with contribution of a speech language pathologist (SLP), and by asking parents about children performance.

The results showed no differences in the average acoustic thresholds for both groups, but the Auditory Performance and Speech Intelligibility of children in the second group were better than in the first group.
