Sound field planarity characterized by superdirective beamforming
The ability to replicate a plane wave represents an essential element of spatial sound field reproduction. In sound field synthesis, the desired field is often formulated as a plane wave and the error minimized; for other sound field control methods, the energy density or energy ratio is maximized. In all cases and further to the reproduction error, it is informative to characterize how planar ...
متن کاملSound Field Analysis Based on Analytical Beamforming
The plane wave decomposition is an efficient analysis tool for multidimensional fields, particularly well fitted to the description of sound fields, whether these ones are continuous or discrete, obtained by a microphone array. In this article, a beamforming algorithm is presented in order to estimate the plane wave decomposition of the initial sound field. Our algorithm aims at deriving a spat...
متن کاملSound Reinforcement Technology Based on Sound Field Reconstruction with Energy Contrast Control
Sound field reconstruction using the least-square method is employed in sound reinforcement applications to achieve uniform sound pressure level (SPL) over audience area in this study. A practical problem that the radiated sound energy decline in audience area appears at low frequencies with conventional least-square method. An approach based on energy contrast control is devised to solve this ...
متن کاملThree-dimensional displays and stereo vision.
Procedures for three-dimensional image reconstruction that are based on the optical and neural apparatus of human stereoscopic vision have to be designed to work in conjunction with it. The principal methods of implementing stereo displays are described. Properties of the human visual system are outlined as they relate to depth discrimination capabilities and achieving optimal performance in st...
متن کاملObjective evaluation of a three-dimensional sound field reproduction system
We present the results of an empirical evaluation of a three-dimensional sound field reproduction system consisting of 32 loudspeakers installed in a hemi-anechoic room at the University of Sydney. This loudspeaker arrangement allows up to third-order, two-dimensional, and fourth-order, three-dimensional Higher Order Ambisonic (HOA) reproduction of sound fields. The ability of this system to re...
