Spatial Hearing Rehabilitation in Noise for Bilateral Cochlear Implant Children

Participants will be instructed to localize a sound emitted in their environment using a virtual reality setup (SPHERE protocol).

Intelligibility threshold is the signal-to-noise ratio (in decibels) for which the subject can repeat 50% of the words heard in a dichotic listening.

The SSQ questionnaire is a clinical subjective scale that allows evaluating of hearing performances in daily life. The questionnaire is divided into 3 main items (A: speech; B: spatial hearing; C: other qualities of hearing) comprising questions with rating scores out of ten.

The tool makes it possible to propose rehabilitation programs adapted to the performance and expectations of each child. This program will manipulate both the ambient sound with varying background noise to simulate daily life environments (i.e. making auditory detection more or less complex), and also manipulate virtual immersive environment (i.e. giving more or less relevant visual cues related to real sound location).
