Analytical Method of 2.5d Exterior Sound Field Synthesis By Using Multipole Loudspeaker Array

Natural Communication Technologies Providing Information through Natural Exchanges that Do Not Interfere with Human Activities

“…We have succeeded in reproducing a sound field using a multipole-loudspeaker array consisting of multiple small speakers closely arranged in a Cartesian grid. This array enables control of the directivity pattern of an arbitrary sound source while being smaller than current speaker arrays [9,10]. These technologies place importance on achieving natural communications to enable users to enjoy a sense of reality without having to wear special devices such as head mounted displays, 3D glasses, or headphones.…”
