T26 - Applications of Binaural Psychoacoustics In Audio—Designing Spatial Audio Techniques for Human Listeners
Presenter:Ville Pulkki, Aalto University - Espoo, Finland
Abstract:
The human spatial hearing mechanisms are based on signal analysis in the auditory system. The monaural attributes of, and binaural differences between ear canal signals form the time- and frequency-dependent spatial cues. The cues are subconsciously analyzed by the brain, which forms the auditory spatial image. This tutorial will review current knowledge of the psychoacoustics of spatial hearing, in particular the perception of directions and distances of sources in free field and in reverberant conditions. Non-linear signal-dependent spatial audio technologies analyze spatial metadata directly from sound field or spatial audio signals with time-frequency-space resolution matching with hearing mechanisms. Optimally, the technologies should designed to reproduce the spatial cues with just good enough resolution without overdoing. The trends in the technologies will be discussed in the tutorial.
