Sounds to appear in directions between the loudspeakers will typically activate neighboring loudspeakers with the same signal when spatially rendered. The resulting interference causes frequency- and position-dependent cancellation in the superimposed sound field.

Conventional multichannel audio reproduction systems for entertainment or communication are not capable of immersing a large number of listeners in a well defined sound field. A novel technique for this purpose is the so-called wave field synthesis.

Parsimonious sound field synthesis using compressive sampling
2009 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics, 2009Reproducing a sampled sound field over a two-dimensional area using an array of loudspeakers is a problem with well-appreciated applications to acoustics and ultrasound treatement. Loudspeaker signal design has traditionally relied on a (possibly regularized) least-squares criterion.

A wave field synthesis approach to reproduction of spatially correlated sound fields
The Journal of the Acoustical Society of America, 2012This article discusses an open-loop wave field synthesis (WFS) approach for the reproduction of spatially correlated sound fields. The main application concerns laboratory reproduction of turbulent boundary layer wall pressure on aircraft fuselages and measurement of their sound transmission loss.

Spatial sound reproduction with wave field synthesis
The Journal of the Acoustical Society of America, 1999Wave field synthesis is a reproduction technique developed at TU Delft, that enables the generation of high-quality three-dimensional spatial sound fields. The benefit of the method is that spatial impressions are highly independent of the position of the listeners within a large listening area.

Psychoacoustic Sound Field Synthesis
2019Sound 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.

Adaptive wave field synthesis for active sound field reproduction: Experimental results
The Journal of the Acoustical Society of America, 2008Sound field reproduction has applications in music reproduction, spatial audio, sound environment reproduction, and experimental acoustics. Sound field reproduction can be used to artificially reproduce the spatial character of natural hearing. The objective is then to reproduce a sound field in a real reproduction environment.

Applications of Sound Field Synthesis
2012Based on the theory developed in the previous chapters, applications of sound field synthesis are presented that allow, e.g., for the synthesis of virtual sound sources with complex radiation properties, focused sources, spatially extended sources, moving sources, and alike. Other practical aspects like the storage and transmission of content for sound

An integrated analysis-synthesis array system for spatial sound fields
The Journal of the Acoustical Society of America, 2015An integrated recording and reproduction array system for spatial audio is presented within a generic framework akin to the analysis-synthesis filterbanks in discrete time signal processing. In the analysis stage, a microphone array “encodes” the sound field by using the plane-wave decomposition.

Perceptual assessment of sound field synthesis
2014Die vorliegende Arbeit untersucht die beiden Schallfeldsyntheseverfahren Wellenfeldsynthese und Nahfeld-entzerrtes Ambisonics höherer Ordnung. Sie fasst die Theorie der beiden Verfahren zusammen und stellt eine Software-Umgebung zur Verfügung, um beide Verfahren numerisch zu simulieren.
