METHOD FOR QUANTITATIVE EVALUATION OF AUDITORY PERCEPTION OF NONLINEAR DISTORTION. PART I. TEST SIGNALS & MEASURE OF QUANTIFICATION
Abstract
The procedure for extracting the signal of nonlinear distortions arising in the sound paths of various devices with the simultaneous presence of frequency and dynamic distortions in the reproduced signal is described. The criteria for estimating their auditory perception and weighting coefficients that take into account the frequency and time response of the signal of nonlinear distortions are proposed. Preliminary experimental data confirming the dependence of the auditory perception of nonlinear distortions as a function of the tone structure of the signal and the spectral distribution of the "noise-to-mask ratio" are obtained.
