The scores mean of auditory perception in normal hearing children was more than children into other groups, significantly (P<0.0005). Also, scores mean of auditory perception in children with cochlear implant was more than children with hearing aids, significantly (P<0.002). 

Conclusion: Auditory perception in children with normal hearing was better than children with cochlear implant or hearing aids. Since, use of cochlear implant and hearing aids led to improvement of auditory perception in deaf children.
