Evaluation of the Effect of a Spatial Localization Training Program on Auditory Comprehension

Study Overview
=================
Brief Summary
-----------------
Hearing comprehension under complex listening conditions is considered to be the central complaint of everyday life for patients with cochlear implants. Localization is one of the cues for listening comprehension. However, only few studies have investigated the effect of spatial localization training on listening comprehension performance in noise. None of these studies correspond to the desire to purpose training by speech therapists while using affordable equipment. The main objective of this study is to evaluate the effect of a spatial localization training protocol in cochlear bi-implanted subjects with post-lingual deafness on their ability to understand in noise. 2 groups of 10 subjects each will be recruited: a patient group and a control group. The patient group will undergo 8 sessions of spatial localization rehabilitation lasting an average of 45 minutes each. After this programme, the pre-test and post- test results obtained will be compared.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of Hearing comprehension performance in noise | MBAA (Marginal Benefic from Acoustical Amplification) scale. Minimal score = 0 and maximal score =540. minimum score means that the patient is unable to repeat phrases and maximal score means that the patient is able to repeats all phrases. | 10 weeks after inclusion | 
| Change of Hearing comprehension performance in noise | 15iSSQ (New 15 items Speech Spatial and qualities of hearing Scale Shoirt Form). Minimum score =0 and maximal score = 150. maximal score means that the patient has a good quality of life and minimum score means that his quality of life is bad. It is a qualitative evaluation. | 10 weeks after inclusion |
