Three-dimensional Perception of Sounds in Military with Acoustic Trauma

No results posted yet for this study

Summary

Spatial hearing capacities of soldiers with acoustic trauma are evaluated in ENT consultations with routine tests (i.e. tonal audiometry, voice audiometry). While the results conclude that soldiers with acoustic trauma have sufficient abilities to carry out professional missions, soldiers report recurring complaints of sound localization (spatial hearing), i.e. difficulties in identifying the position of sound sources in their environment. However, there is currently no objective test to identify and objectify these complaints of spatial hearing.

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.

Conditions

Interventions

DIAGNOSTIC_TEST

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).

DIAGNOSTIC_TEST

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.

BEHAVIORAL

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.
