138 - Binaural psychoacoustic model applicable to sound quality estimation
Bures Z., Rund F.
Abstract
In relation to lossy audio compression algorithms, the need for assessment of perceived sound quality of the compressed signal arises. Objective sound quality evaluation methods require appropriate models of human hearing system. In the paper a binaural psychoacoustic model is presented. The model comprises a monaural and a binaural processing stage, the former being based on an active nonlinear cochlear model including the effect of IHC, the latter consisting of a two-dimensional comparison of the right-ear and left-ear signal. Approximation of the influence of outer and middle ear employs the transfer properties of acoustic waveguides.
