Super-Directive Loudspeaker Array for the Generation of Personal Sound Zone
A sound manipulation technique is proposed for selectively enhancing a desired acoustic property in a zone of interest called personal sound zone. In order to create the personal sound zone in which a listener can experience high sound level, acoustic energy is focused on only a selected area. Recently, two performance measures indicating acoustic properties of the personal sound zone –acoustic brightness and contrast – are employed to optimize driving functions of a loudspeaker array. In this paper, firstly some limitations of individual control method are presented, and then a novel control strategy is suggested such that advantages of both are combined in a single objective function. Precise control of sound field with desired shape of energy distribution is made possible by introducing continuous spatial weighting technique. The results are compared to those based on the least-square optimization technique.
