Abstract

Abstract Introduction: Hearing impairment affects all aspect of individual life, especially auditory perception, while use of cochlear implant or hearing aids has been associated with appropriate effects in auditory performance. The aim of the present research was to comparing auditory perception in children with cochlear implant, hearing aids and normal hearing in Tehran province. Materials and Methods: In this analytic and comparative research, were participated 60 male children aged 5–7 years. They were divided into three groups and each group was consisted 20 children.

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.
