Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Distinguishable inter-contact distances (ICD; e.g. channel discrimination) as determined by two separate tests. We are interested in the correlation between the found ICDs in both tests. Also, we want to improve the first version of the software, leading to more userfriendliness. | — |
Secondary
| Measure | Time frame |
|---|---|
| Relate the results from both methods to position in the cochlea and consonant-vowel-consonant (CVC) scores, and possibly to patient demographics (e.g. time since implantation, age). We also want to compare the results of this study to the group we included earlier, to see if the results are similar and the algorithm is performing as expected. | — |
