- Primary Outcome Measures
Name Time Method <p>The different outcome measures are speech intelligibility (in terms of words<br /><br>correct as well as the signal to noise ratio (SNR) at which 50% is correctly<br /><br>repeated), detectability of differences between temporal settings and overall<br /><br>preference (derived from paired comparison ratings). Results of the NH group<br /><br>are compared with results of the HI group.</p><br>
