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