Primary Outcome Measures

Name	Time	Method
<p>Per group the speech reception threshold (SRT) at different degrees of<br /><br>distortion of the time and frequency signal cue.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>1. Normative data for normal hearing on these tests.<br /><br>2. For individuals the performance on the different modifications of the<br /><br>Digit-In-Noise (DIN) tests w.r.t. the performance on the DIN test itself. </p><br>
