Acoustic Element and Array Design Approaches
Wave propagation theory relevant to array design is summarised. Broad-fire and End-fire array types are considered with regard to array element directivity and point source behaviour in particular. Factors including the aperture limit, spatial aliasing, truncation effects and driver directivity control techniques are considered and strategies summarised. A novel approach to driver design allowing flexible control over directivity at manufacture is then explored and a prototype reported on. It is verified that the aperture limit can be exceeded. The implications for array design and reciprocal capture approaches are considered. Patent applications apply to aspects of this work.
