AB  - A novel acoustic lens has been devised which allows the acoustic radiation field of two or more transducers to be coupled in phase such that the resultant acoustic radiation pattern is interference-free at all frequencies, and displays wide and nearly frequency independent beam width. The lens is utilized in the high frequency transduction system of a loudspeaker array in order to achieve high frequency beam widths which approach that of the low frequency components while eliminating beaming, upper frequency beam collapse, and combing.
