RPG Wrote The Book On Diffusion… and Absorption

The history and evolution of the sound diffusion industry cannot be written without including the pioneering contributions made by RPG Diffusor Systems, Inc., which continue to shape the future of the industry. RPG introduced the first commercial sound diffusor 20 years ago on December 15, 1983 and its products, research, publications and educational efforts have brought the industry to where it is today. Dedication and commitment to fundamental acoustics research have propelled RPG into its current position of industry leadership and innovation in the commercial architecture, pro audio and home theater markets. To help celebrate these two decades of innovation, RPG is publishing a comprehensive acoustical text book and launching a new generation of sound diffusors.

New Book
The history of what is currently known about diffusion and absorption has been compiled in a major new research text for Spon Publishers entitled “Sound Absorbers and Diffusers: Theory, Design and Application”, authored by Dr. Trevor J. Cox and Dr. Peter D’Antonio. Publication is expected in the beginning of 2004. View Table of Contents. Available February 13, 2004 on Amazon

Next Generation of Diffusors
In addition, on this 20th Anniversary, RPG launches a new generation of diffusive surfaces based on the patent pending concept of Aperiodic Modulation of a Single Asymmetric Base Shape. This new technology is the culmination of 20 years of research on optimizing the performance of number theory diffusors and introducing new custom optimized architectural diffusive shapes and materials. The new modulated and optimized traditional QRD® looking diffusors are called Modffusors™ and the new curve optimized and modulated shapes are called Waveform™. Both new products can be used to “tile” large areas without periodicity effects, offering the shape of the future and the highest level of diffusive performance to date.

Stay tuned and RPG will be announcing events throughout the year to thank the many acousticians, architects, sound contractors, studio and home theater designers who have help us make this dream a reality.
