Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main outcome will be the performance on the Amsterdam-Oldenburg Bilateral Benefit Battery for cochlear implants (AO-BBB-ci) test battery. This test battery evaluates the performance for speech perception in background noise with a spatial separation between the sound sources, horizontal localization, and listening effort. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome measures will be self-reported benefits in everyday listening situations assessed with the Speech, Spatial and Qualities Hearing Scale (SSQ), generic quality of life questionnaire scores (Health Utilities Index, HUI) and disease specific quality of life questionnaire scores (Nijmegen Cochlear Implant Questionnaire, NCIQ, and Tinnitus Handicap Inventory (THI). | — |
