TABLE I.
The RMS error and correlations between the model predictions and listener responses for HASPI w2 (proportion keywords correct) fit to the NH and HI data. The results are averaged over the listeners in each hearing group. The RMS error and correlation values are the mean of 10 000 bootstrap replications of the model output.
