AB  - While non-linear distortion in loudspeakers decreases audio quality, the perceptual consequences can vary substantially. This paper investigates the metric Rnonlin [1] which was developed to predict subjective measurements of sound quality in nonlinear systems. The generalizability of the metric in a practical setting was explored across a range of different loudspeakers and signals. Overall, the correlation of Rnonlin predictions with subjective ratings was poor. Based on further investigation, an additional normalization step is proposed, which substantially improves the ability of Rnonlin to predict the perceptual consequences of non-linear distortion.
