#1 Steerable highly directional audio beam loudspeaker [PDF] [Copy] [Kimi]

Authors: Dirk Olszewski ; Fransiskus Prasetyo ; Klaus Linhard

This paper presents a method of steering audible sound beams generated by parametric arrays in air. A hybrid system consisting of combined electronic / mechanical phased array technique is used. Although commercially available emitter technology has been used and therefore several guidelines known from prior-art phased arrays could not be realized, sufficient beam steering performance has been reached.
