Abstract

A series of at least three loud speakers is set one in each of at least three walls forming alternately oppositely opening dihedral angles with each other. The center-to-center distance between the loud speakers is less than 10 times the wavelength of the upper limiting frequency of the sound frequency band. The loud speakers are excited by the same signal source, and a stronger interference field is produced than if the sound emanated from a planar or spherical surface.
