Primary Outcome Measures

Name	Time	Method
<p>The main outcome measures are the detection threshold for speech distortion and<br /><br>preference for different degrees of noise reduction. We will look for relations<br /><br>between those measures and other audiological characteristics (pure tone<br /><br>threshold, acceptable noise level, frequency resolution, temporal acuity, or<br /><br>speech intelligibility).</p><br>
