This work demonstrates a comprehensive methodology for capture, analysis, manipulation,
and reproduction of spatial sound-radiation. As the challenge herein, acoustic events need …

The radiation patterns of acoustic sources have great significance in a wide range of
applications, such as measuring the directivity of loudspeakers and investigating the …

Spatial sound reproduction systems aim to produce a desired sound field over a volume of
space. At high frequencies, the number of loudspeakers required is prohibitive. This paper …

The measurement of reverberation time is an essential procedure for the characterization of
the acoustic performance of rooms. The values returned by these measurements allow us to …

The quote from Pierre Boulez, given as an epigraph to this article, inspired French
researchers to start developing technology for spherical loudspeaker arrays in the 1990s …

Active control of sound has been employed to reduce noise levels around listeners' head
using destructive interference from noise-canceling sound sources. Recently, spherical …

Spherical loudspeaker arrays, as concerned within this work, are a finite set of transducers
distributed on the surface of a sphere or platonic solid. The purpose of these arrays is to …

Sound directivity control is made possible by a compact array of independent loudspeakers
operating at the same frequency range. The drivers are usually distributed over a sphere …

Spherical loudspeaker arrays have been recently studied for directional sound radiation,
where the compact arrangement of the loudspeaker units around a sphere facilitated the …

This paper proposes a method to design a planar first-order loudspeaker array structure for
global active noise control. Compared with the traditional spherical loudspeaker array, the …
