Spatial Hearing Perception in Bilateral Cochlear Implant Children

France36 participantsStarted 2019-01-24

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
