Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The investigators have developed a new approach (SPHERE) based on virtual reality and 3D motion tracking, allowing us to evaluate and record the spatial hearing performance of subject with hearing deficit. This system allowed us to highlight localization deficits in three-dimensional space.
This project explores and quantifies the spatial hearing impairments of soldiers with acoustic trauma. The quantification of the spatial hearing capacities will allow to define a specific rehabilitation strategy of spatial hearing deficits.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Military person with acoustic trauma (experimental group)
Active or reserve military member, diagnosed with acoustic trauma for at least one month. Participants will be instructed to localize a sound emitted in their environment using a virtual reality setup.
SPHERE protocol : Spatial hearing performances test
Participants will be instructed to localize a sound emitted in their environment using a virtual reality setup (SPHEAR protocol).
French Matrix Test : audiology test of speech in noise perception
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.
SSQ15 questionnaire of life : (The Speech, Spatial and Other Qualities of Hearing Scale)
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.
Normal hearing volunteers (control group)
Person without known hearing loss.
SPHERE protocol : Spatial hearing performances test
Participants will be instructed to localize a sound emitted in their environment using a virtual reality setup (SPHEAR protocol).
