With a high sound quality stimulated by the electrical device and a large inclusion in medical insurance, the number of cochlear implant recipients has been rapidly increased in Korea. Today, it is not surprising that early implanted young children with congenital deafness show a similar performance to their normal hearing peers in speech perception. However, the cochlear implant users still have a trouble to enjoy music. This review study aims to introduce briefly about acoustic components that required to perceive the music and understand a relationship between cochlear implantation and temporal fine structure. For the pediatric implant users who have less experience on acoustical sound features but are much familiar with the electrically stimulated sound, perceiving the music seems to be challengeable due to the lack of temporal fine resolution related to pitch and timbre among various components of music. Four representative test batteries for evaluating the recipients’ ability of the music perception were mentioned and effective auditory music trainings were discussed with analysis of related investigations. Unlike hearing aids users who usually depend on fitting algorism for better music quality, the cochlear implant users need systematic training to improve their music perception ability. In conclusion, advancement of speech processing technology which can provide accurate information about the temporal fine structure of incoming music to the recipients needs to be developed. Also, a practical application of music training should be recommended as a part of auditory training for the cochlear implant users.
