Scatterplots comparing (a) better-ear HASPI v2 predictions to the binaural subject intelligibility scores using an audiogram scale factor of 1, and (b) binaural HASPI predictions to the binaural subject intelligibility scores using an audiogram scale factor of 1.5. Each point represents the data for a single processing condition averaged over repetitions and either NH or HI subjects for that condition. Data for the NH subjects are plotted using open circles and data for the HI subjects are plotted using filled squares.
