To the question of forming omnidirectional sound radiation by planar arrays of loudspeakers

S.А. Luniova, I.N. Sanzhara
Annotations languages:

The possible configurations of planar loudspeaker arrays, which excitation coefficients are given based on a set of Bessel functions, were analyzed. The benefits of building rectangular arrays, in which linear Bessel arrays are used horizontally and vertically, were discovered.
Keywords: Bessel array, directional characteristic, directivity pattern, loudspeaker, Bessel functions of the first kind
