- Primary Outcome Measures
Name Time Method <p>The primary study parameters are the differences in response between pairs of<br /><br>CI electrodes. The response in case of the EEG measurement (passive task) is<br /><br>the neural power at frequencies of interest, determined by the two stimulation<br /><br>patterns of the two CI electrodes. For the reaction-time method (active task),<br /><br>the response is the manual response-reaction-time to a perceived change in the<br /><br>sound.</p><br>
- Secondary Outcome Measures
Name Time Method <p>The secondary study parameter is the correlation between outcomes of the speech<br /><br>and spectro-temporal modulation tests as determined with the App and with the<br /><br>standard lab test methods.<br /><br>Further study parameters are the electrode impedances and eCAPs.</p><br>
