Abstract
This paper is concerned with the perception of dynamic range in the nonlinear system. The work is differentiated from the generic investigation of ‘sound quality’ which is usually associated with studies of nonlinear distortion. The proposed hypothesis suggests that distortion products generated within the compressive type nonlinear system are able to act as loudness compensator for the associated amplitude compression in the loudness function. The hypothesis is tested using the Time-Varying Loudness model of Glasberg and Moore (2002) and further tested using AB scale hidden reference type listening test methods. The Loudness Overflow Effect (LOE) is introduced and bandwidth is shown to be a significant limiting factor. Results and immediate implications are briefly discussed.
