Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
A novel methodology based on virtual reality and 3D motion capture protocol in an immersive reality system has recently been developed to evaluate and record spatial hearing abilities of norm-hearing (NH) listeners and CI adults in 3D. The results revealed worse sound localization in 3D for CI users compared to NH participants, and interestingly noted that head movements could improve sound localization performances, leading to a possible track for auditory rehabilitation.
The aim of this study is to explore spatial hearing in CI children with the protocol already tested in CI adults. This protocol will be adapted to children over eight years old. Children will have to perform a sound localization task in 3D without any feedback of performances. The knowledge improvement in pediatric sound localization will lead to develop a specific spatial rehabilitation in cochlear implant children.

cochlear implant children
18 cochlear implant children wil include in this study
behavioral exploration of spatial hearing performances
Normal hearing children and cochlear implant children will have to localize a sound source in three dimensional space by using a virtual reality system (Neuro immersion platform). The experiment will last thirty minutes.
For normal hearing children, this experience will be performed at the inclusion visit.
For cochlear implant children, this experience will be performed 28 days (+/- 2 days) after inclusion.
The Speech, Spatial and Qualities of Hearing Scale (SSQ) questionnaire (for cochlear implant children and their parents)
For cochlear implant children and their parents, a SSQ questionnaire will be given and completed during the first visit (at the inclusion).
This questionnaire offers a version for parents of children with hearing loss ("SSQ Parents CI") and a version for the children themselves ("SSQ Children CI").
The Speech, Spatial and Qualities of Hearing Scale (SSQ) questionnaire (for parents of CI children)
The SSQ questionnaire for Parents of CI children is composed of three distinct sections (A, B and C).
Each section will be filled separately by parents of CI children with one of the study collaborators during 3 telephone calls spaced 1 week apart. Thus, section A will be completed 7 days (+/- 2 days) after inclusion , section B 14 days (+/- 2 days) after inclusion, and section C 21 days (+/- 2 days) after inclusion.
