Primary Outcome Measures

Name	Time	Method
-Calculation of the discrimination function<br><br>-Calculation of the perceptual equivalence of digits by specifying the mean 95%<br><br>-Confidence intervals between the speech intelligibility thresholds of the digits (SVS_Ziffer)<br><br>-Calculation of the reproducibility of the results (average test-retest reliability): DIN EN ISO 8253-3 specifically requires the indication of the mean test-retest reliability in percentage points. This reliability is the outcome of squared difference between the measurement results (adaptive measurements) of test and retest - averaged over the subjects. From this value the square root is calculated and multiplied by 2. The mean reliability test against retest) is considered to be the mean 95% confidence interval indicated by the subjects.

Secondary Outcome Measures

Name	Time	Method
-average test duration (in minutes) -Training effects (number of adaptive measurements that are necessary until the deviation of the measurement results for the SVS is <1dB)<br>-Compared to established language tests, i.e. the determined speech intelligibility threshold (SVS_DTT) from the reference curve of the DTT is compared with the reference values ??of the Oldenburg sentence test (OLSA)
