- Primary Outcome Measures
Name Time Method <p>Main study parameters are performance in psychophysical tests for expressed in<br /><br>the relevant units, such as speech reception threshold (SRT), ripples per<br /><br>octave (RPO), just noticeable difference (JND) and correct percentages.</p><br>
- Secondary Outcome Measures
Name Time Method <p>Secondary study parameters are subject characteristics possibly influencing<br /><br>performance and discrimination abilities like using a cochlear implant, type of<br /><br>implant, electrode position in the cochlea, duration of implantation, duration<br /><br>of hearing loss/deafness, recent Consonant-Vowel-Consonant (CVC) scores and<br /><br>demographics.</p><br>
