METHOD OF THE MULTITONAL SIGNAL CONSTRUCTION IN DECISION SUPPORT SYSTEMS ACS
Main Article Content
Abstract
Subject: The article deals with the issues of creation of a psychoacoustic model of perception of sound quality of sound signals, the development on its basis of the method of creating a multi-tonal signal, which provides a high correlation with subjective evaluation. Purpose: to develop a multitoon signal creation method. Objective: To analyze the distortion of the sound signals that arise during reproducing them on the sound reproduction devices. Classify these distortions and assess the extent of their impact on subjective assessment. Allocate the most significant of them in terms of impact on the quality of sound. Investigate modern methods for assessing the quality of reproduction of sound signals, standards and recommendations devoted to this task; to evaluate the effectiveness of modeling the human auditory system used in the development of these methods; formulate the scientific and applied requirements for developing objective quality assessment method. Conclusions: The application of the developed method will allow obtain results that coincide with the data of subjective and statistical examinations (SSE) with the accuracy required for practice.
