Cochlear Impant Children Clinical Trial
Official title:
Spatial Hearing Perception in Bilateral Cochlear Implant Children
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.
