Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who are French speakers and meet the criteria for cochlear implantation.
✕Probably not a fit
Patients with retro-cochlear pathologies or significant residual hearing in the contralateral ear may not benefit from this study.

What this trial studies
This study aims to compare a tonotopy-based fitting strategy (TFS4) with a conventional fitting strategy (FS4) in patients receiving cochlear implants combined with hearing aids. The primary focus is on assessing speech recognition in noisy environments, while secondary objectives include evaluating performance in quiet settings and overall auditory skills. The study seeks to address the variability in outcomes experienced by bimodal users by optimizing the frequency matching between the cochlear implant and the hearing aid. Participants will undergo both fitting strategies to determine which provides better auditory outcomes.
Why it matters
Potential benefit: If successful, this study could enhance speech recognition and overall auditory experience for patients using cochlear implants and hearing aids.
How similar studies have gone: While there is variability in outcomes for bimodal users, this approach is innovative and aims to improve existing fitting strategies, suggesting potential for success based on previous findings.
