Acoustic coupling and directivity control

Abstract

This article deals with the kind of acoustic sources, how waves propagate and the criteria which allow to couple sources. It also explains why and how to control the directivity, as well as what is a bad directivity (with real examples). Designing such a product requires knowledge of mechanical manufacturing, electronics, acoustics, design, etc. There is not a “recipe” to design a professional soundsystem because applications are wide. Directivity is just one problem and criteria out of many. Another goal of this article is to explain few of many problems while designing a professional soundsystem.
