Convention Paper

Geometric Considerations for Multichannel Reinforcement System Loudspeaker Placement

Authors: Collins, Glen C.

AES Convention 92 · Paper 3301 · March 1992

Abstract

Multichannel sound reinforcement systems can provide natural and realistic imaging of live events only when the loudspeaker placement properly considers the physical geometry of the staging area and the maximum audience viewing angles. Many existing multichannel designs have provided good sound imaging but only for those audience seats which are physically located between the outermost loudspeakers. This paper proposes limits and constraints for loudspeaker placement in order to provide natural sound imaging to the majority of audience seats, even those seats which are at extreme horizontal angles to the stage. The issues of loudspeaker positioning (elevation, front-to-back, and left-to-right), channel coverage areas, device beamwidth, and source-to-channel assignment are examined.
