| Outcomes on audiological tests: NVA phoneme scores, DIN test, and Matrix test. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary study parameters are comparisons between scoring mechanisms (clinician vs. self-scoring) of the tests mentioned above. We will also compare outcomes on the different tests both within-subjects and between subjects. Additionally, secondary study parameters are subject characteristics possibly influencing performance and discrimination abilities. Demographic data will be gathered to accurately describe the study sample, such as type of implant, experience with implant, duration of deafness etc. | — |
