T3 - Foundations and Practical Aspects of Sound Field Synthesis
Presenters:Sascha Spors, University of Rostock - Rostock, Germany

Abstract:
Sound Field Synthesis (SFS) aims at the physical synthesis of sound fields within a predefined listening area by an ensemble of loudspeakers. Wave Field Synthesis (WFS) and higher-order Ambisonics (HOA) are two prominent representatives of Sound Field Synthesis. This tutorial outlines the history of SFS, its acoustic foundations, and discusses how practical solutions can be achieved in terms of loudspeaker arrays and digital signal processing. The practical realization by such systems involves various approximations and limitations. The technical and psychoacoustic impact of these is reviewed. This tutorial concludes with an outlook on recent research results and developments.
