Primary Outcome Measures

Name	Time	Method
<p>Test results on spectral loudness summation and binaural loudness summation<br /><br>will be analysed for descriptive statistics. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Secondary study parameters that will be studied are the differences between<br /><br>types of hearing loss and the kind of BB noise (high frequency noises and low<br /><br>frequency noises). Furthermore we want to evaluate the loudness based fitting<br /><br>method Fit2Ears to the NAL-NL2 fitting method by using the SRT results. </p><br>
