Primary Outcome Measures

Name	Time	Method
<p>Primary outcome measures: amplitudes and latencies of the electrically evoked<br /><br>compound action potential (eCAP); secondary outcome measures: amplitudes and<br /><br>latencies of electrocochleography.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>In order to assess the clinical applicability/usefulness of the aforementioned<br /><br>measurements, these experimental measurements will be compared to routinely<br /><br>(clinically) obtained data such as etiology, degree, and duration of hearing<br /><br>loss, and speech intelligibility scores.</p><br>
