Psychoacoustic Sound Field Synthesis

Abstract

Sound field synthesis approaches aim at creating a desired sound field. Conventionally, these approaches are physically-motivated. Acoustical properties define the desired sound field. A perceptual evaluations of the listening experience follows the technical implementation. Psychoacoustic sound field synthesis, as introduced in this chapter, has another paradigm. Here, psychoacoustical properties determine the desired sound field. This allows for implementation of auditory Threshold thresholds and integration times in the derivation of the sound field synthesis core. This allows for inaudible reduction of temporal, spatial, and spectral resolution. The result is a natural, spatial listening experience and a precise source localization for multiple listeners with comparably low computational efforts and inaudible synthesis errors.
