Primary Outcome Measures

Name	Time	Method
<p>The main study parameters in the study are: (1) the pupil response evoked<br /><br>during listening to speech in noise and (2) the brain activation during<br /><br>listening to sentences in noise. Sentences will be presented in noise, using a<br /><br>wide range of signal-to-noise ratios (SNRs) covering very low to high<br /><br>comprehension levels. </p><br>
