A brief review of independent sound zone technology

Independent sound zone technology aims to construct multiple independent sound zones with different sound fields, which are independent of each other and do not interfere with each other, and has wide research value and application prospects in today’s increasingly complex received information. To help scholars preparing to investigate independent sound zone techniques get started quickly, this paper presents research advances in three independent sound zone construction methods based on loudspeaker arrays, sound field reconstruction and parametric array loudspeakers, including the implementation principles and optimization schemes of these methods.
