Abstract

Planarity panning (PP) and planarity control (PC) have previously been shown to be efficient methods for focusing directional sound energy into listening zones. In this paper, we consider sound field control for two listeners. First, PP is extended to create spatial audio for two listeners consuming the same spatial audio content. Then, PC is used to create highly directional sound and cancel interfering audio. Simulation results compare PP and PC against pressure matching (PM) solutions. For multiple listeners listening to the same content, PP creates directional sound at lower effort than the PM counterpart. When listeners consume different audio, PC produces greater acoustic contrast than PM, with excellent directional control except for frequencies where grating lobes generate problematic interference patterns.
