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