Effort variation regularization in sound field reproduction

Journal of the Acoustical Society of America, 2010
In this paper, active control is used in order to reproduce a given sound field in an extended spatial region. A method is proposed which minimizes the reproduction error at a number of control positions with the reproduction sources holding a certain relation within their complex strengths.

Evolutionary array optimization for multizone sound field reproduction

The Journal of the Acoustical Society of America, 2022
Multizone sound field reproduction aims to generate personal sound zones in a shared space with multiple loudspeakers. Traditional multizone sound field reproduction methods have focused on optimizing the source strengths given a preset array configuration.

Robust sound field reproduction integrating multi-point sound field control and wave field synthesis [PDF]

2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011
For a reproduced sound field, the competing goals between the listening area and reproduction accuracy in an actual environment is one of the most important problems in sound field reproduction using loudspeakers. In this paper, we propose a new method of balancing these goals with absolute accuracy using an inverse filter of the room acoustics: the ...

Sound Field Reproduction using the Lasso

IEEE Transactions on Audio Speech and Language Processing, 2010
Reproducing a sampled sound field using an array of loudspeakers is a problem with well-appreciated applications to acoustics and ultrasound treatment. Loudspeaker signal design has traditionally relied on (possibly regularized) least-squares (LS) criteria.

Sound field reproduction as an equivalent acoustical scattering problem

The Journal of the Acoustical Society of America, 2013
Given a continuous distribution of acoustic sources, the determination of the source strength that ensures the synthesis of a desired sound field is shown to be identical to the solution of an equivalent acoustic scattering problem. The paper begins with the presentation of the general theory that underpins sound field reproduction with secondary ...

Sound Field Reproduction With Energy Constraint on Loudspeaker Weights

IEEE Transactions on Audio Speech and Language Processing, 2012
Audio rendering problems are not always well-posed. An approach is devised for solving ill-posed sound field reproduction problems using regularization, where the Tikhonov parameter is chosen by upper bounding the summed square of the loudspeaker weights. The method ensures that the sound in the room remains at reasonable levels.
