Convention Paper

Performance Acoustics: The Importance of Diffusing Surfaces and the Variable Acoustics Modular Performance Shell-VAMPS-

Authors: D'Antonio, Peter

AES Convention 91 · Paper 3118 · October 1991

Abstract

There has been significant research in stage acoustics within the last decade. This research is focused on determining the appropriate distance, disposition and composition of sound scattering surfaces on the stage enclosure. The acoustical design of stage enclosures must try to satisfy the sometimes contradictory requirements for solo performance, chamber group, full orchestral and chorus as well as providing sufficient sound projection into the hall. Since the introduction of the QRD trademark in 1983, there has been an expectation that, in addition to improving critical listening spaces, these new surfaces would enhance the acoustics of stage and pit performance environments. The case studies presented in the paper are part of an ongoing research program to satisfy these expectations and develop a new generation performance acoustical shell. This goal has been realized in the evolution of a variable acoustics modular performance shell called VAMPS trademark.
