Summary

We recently developed a new Neuro-immersion system based on virtual reality and 3D (dimension) motion tracking. This tool makes it possible to evaluate and record the spatial localization performance of sounds and to highlight localization deficits in the three dimensions of space in deaf patients. Unfortunately, there is currently no suitable support to compensate for these localization deficits. However, the discomfort felt by the patients is clearly verbalized. Thanks to the new virtual reality system, we are now able to develop a training protocol based on spatial sound localization tasks.

Interventions

Type	Name	Description
BEHAVIORAL	Training Protocol n°1 first at Visit 1, then, Training Protocol n°2 at Visit 2	During Protocol 1 (visit 1), participants of Group A will perform auditory spatial localization tasks with sensory feedback and during Protocol 2 (visit 2), they will perform auditory tasks without any notion of spatial localization. The 2 visits will be spaced at least 2 weeks (Wash-out). The effects of each of the protocols on spatial location hearing abilities will be specifically assessed by comparing the results of the different assessments (SPHERE and Visual Discrimination Test) obtained before and after each protocol.
