A Practical Step-by-Step Guide to the Time-Varying Loudness Model of Moore, Glasberg, and Baer (1997; 2002)

Document Thumbnail

In this tutorial article we provide a condensed, practical step-by-step guide to the excitation pattern loudness model of Moore, Glasberg, and Baer [J. Audio Eng. Soc., vol. 45, 224–240 (1997 Apr.); J. Audio Eng. Soc., vol. 50, 331–342 (2002 May)]. The various components of this model have been separately described in the well-known publications of Patterson et al. [J. Acoust. Soc. Am., vol. 72, 1788–1803 (1982)], Moore [Hearing, 161-205 (Academic Press 1995)], Moore et al. (1997), and Glasberg and Moore (2002). This paper provides a consolidated and concise introduction to the complete model for those who find the disparate and complex references intimidating and who wish to understand the function of each of the component parts. Furthermore, we provide a consolidated notation and integral forms. This introduction may be useful to the loudness theory beginner and to those who wish to adapt and apply the model for novel, practical purposes.
