Study Summary
This study aims to collect data in newly implanted cochlear implant-recipients to inform future development of fitting methods to optimally and efficiently program a cochlear implant.
Primary Outcome
To determine whether the loudness target (LT) map provides non-inferior speech understanding in quiet compared to the behavioural map. Percentage of correct monosyllabic word scores in quiet (S0) at 50 dB SPL averaged across the sessions at visit 4 and visit 5. The higher the score, the better the outcome.
Interventions
- DEVICE Categorical loudness scaling based fitting using the research fitting system.
- DEVICE Behavioural fitting using Custom Sound Suite (CSS 6.3) Software
