Course Description

The goal of this course is to provide the fundamental knowledge on the way the human hearing system functions, and how these phenomena are applied in various fields of modern technology. The introductory part of the course deals with the physiology of the human hearing system and the consequential course of the hearing process. The focus is then shifted to the binaural nature of human hearing and the related sound source localization mechanisms (interaural level and time differences and the head-related transfer functions. The masking effect and the closely connected perceptual audio coding are described next. The field of psychoacoustics is introduced through the psychoacoustic parameters such as loudness, sharpness, roughness, fluctuation strength and tonality of sound, with the emphasis on loudness and pitch perception. The term and the field of sound quality is introduced. Methods of subjective (perceptual) evaluation of sound-related phenomena through listening tests are described. Special attention is given to speech intelligibility as a complex phenomenon influenced by many factors. The influence of the listening space on the listening experience is addressed as well. Auralization via binaural (and other types of) synthesis is presented as the basis for creating virtual sound environments. The final part of the course deals with the analyses procedures of the overall sound image in a sound environment.
