Some Comments on the Acoustic Coupling of Elements in an Array

Abstract

The effects of acoustic coupling between radiators is investigated for linear and planar acoustic arrays. To provide a simple model for calculation and inversion of the acoustic impedance matrices, spherical radiators are chosen. Considerations of total radiated beam power are addressed. The principal effect of element interaction on array performance found is in the effective impedance of individual radiators in the array. Keywords: Acoustic arrays; Linear arrays; Acoustic impedance; Acoustic beams.
