Abstract
Sound field control (SFC) technology enables the active management of audio delivered within an acoustical environment. It includes three research directions: sound field reproduction, personal audio systems, and active noise control. Sound field reproduction uses loudspeaker arrays to replicate a sound field in a target region; personal audio systems extend sound field reproduction over multiple regions so that different listeners can hear personalized audio in a shared space; and active noise control aims to cancel the original sound field in the target area by generating a secondary sound field. In this paper, we briefly review the advances of the three different types of techniques with a discussion of their algorithms and applications.
