(Color online) Boxplot of spectral ripple-phase discrimination threshold (SRD) for listeners with normal hearing and hearing loss. Listeners with normal hearing had better ripple density discrimination thresholds (i.e., better SRD) compared to listeners with hearing loss. The + symbols represent outliers. Outliers were defined as data values greater than 2 times the interquartile range.
