Clinical Trial Summary

Hearing aids restore efficiently some auditory functions in age-related hearing loss (ARHL or presbycusis) providing to the elderly an access to oral communication and a return to social life. However, a most of the assessments of their efficacy focus on speech recognition. Spatial hearing and localization are anothers important auditory functions merely evaluated. The purpose of this study is to evaluate the hearing aids benefits for spatial hearing.

Description:

The main objective is to evaluate the hearing aids benefits for spatial hearing with a multidisciplinary approach combing psychophysics, and Positron Emission Tomography (PET) brain imaging in a before/after experimental design. The novelty of the proposal is both theoretical and methodological: the team aim is to identify neural correlates of spatial hearing after hearing rehabilitation and evaluate the evolution of spatial hearing abilities once subjects with presbycusis are fitted with hearing aids. The assessment of spatial hearing processing will rely on both a virtual visuo-auditory 3D immersive platform and functional neuroimaging using PET scan. This project will provide crucial elements for understanding and improving the rehabilitation of age-related hearing loss.

Primary	level of brain activity	level of brain activity (in ml/100g/min) measured in the auditory regions in PET when the subject performs a spatial localization task	Month 12
Secondary	Life quality by Speech, Spatial and Qualities of Hearing (12)	Speech, Spatial and Qualities of Hearing is a questionnaire specific to the quality of hearing. It has 3 sections; speech hearing, spatial hearing and quality of hearing. This questionnaire contains 15 items evaluated on a scale to 0 (not at all) to 10 (perfectly).	Month 12

Secondary	life quality by Hearing Handicap Inventory For The Elderly Screening (12)	Hearing Handicap Inventory For The Elderly Screening contains 10 items to identify the social and emotional difficulties encountered by the subject due to his deafness according to specific situations. It makes it possible to detect the handicap perceived by the person (the higher the score, the greater the perception of the handicap due to hearing loss).	Month 12
