Sound field reproduction for consumer and professional audio applications
2013 14th International Workshop on Image Analysis for Multimedia Interactive Services (WIAMIS), 2013Sound field reproduction has been developed for the last twenty years in research laboratories but has only made its way into the professional market and consumer markets a few years ago. Sound field reproduction addresses the major problem of classical channel based reproduction (two channel stereophony and its derivation: 5.1 and 7.1) that can only ...

ACTIVE CONTROL OF ACOUSTIC FIELDS AND THE REPRODUCTION OF SOUND
Acoustics '93, 1994Abstract In recent studies of the active control of acoustic fields analytical methods and multi-channel signal processing techniques have been used that can be usefully applied to problems in sound reproduction. In this paper several aspects of the reproduction of sound are considered. First, the possibility is considered of the perfect reproduction

Towards optimal loudspeaker placement for sound field reproduction
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013With a view to the suppression of unwanted sound, a planar array of loudspeakers is used to recreate a sound field in a nearby cubic listening area. Using free-space propagation, the formulation for selecting optimal locations of loudspeakers is developed so that numerical experiments can give a feel for the best possible suppression. First, to provide

Comparison of Loudspeaker Placement Methods for Sound Field Reproduction
IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2016This paper presents a comparison between several loudspeaker placement methods for sound field reproduction (SFR). The goal of these placement methods is to reduce the SFR error under a power constraint by selecting suitable locations for the loudspeakers. The first method is based on singular value decomposition of the acoustic transfer function (ATF)

Modeling and reproduction of sound field by moving complex sound source
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023Previously, Wave Field Synthesis (WFS), Near-field Compensated Higher-Order Ambisonics (NFC-HOA), Boundary Surface Control (BoSC), and the Spectral Division Method (SDM) have been proposed as sound field synthesis methods. These methods are based on matching the acoustic physical quantities at the boundary of the reproduced sound field with those of ...

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.

The study of sound field control using reproduction of plane-wave sound
The Journal of the Acoustical Society of America, 1996A system for teleconferences using a medium-size screen with 3-D sound reproduction having proper incoming direction of the talker’s speech by using the wavefront reproduction technique is discussed. In the ordinary configuration, the multiple loudspeakers are spanned in front of the screen.

Multizone wideband sound field reproduction
2014This thesis deals with the problem of multizone wideband sound field reproduction using an array of loudspeakers. A pressure matching approach is researched to control the sound field within the zones through the calculation of loudspeaker weights. The loudspeaker weights are computed first using a regularized least-squares (LS) approach and then a ...
