About

Spatial hearing in cochlear implant (CI) users is a challenging investigation field since no studies have explored yet spatial auditory perception in three-dimensional space (3D). Moreover auditory rehabilitation after cochlear implantation is totally devoted to speech rehabilitation to date.

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.
