Modviewsor™ 1D Acrylic Sound Diffuser
To minimize the lobing inherent in number theory sound diffuser designs, which compromises the uniformity of the scattering, and simultaneously provide a light transmitting solution, RPG developed the Modviewsor™. The computer optimized Modviewsor™ offers significantly better performance than its predecessor, the Diviewsor®, and in a shallower profile. Where the performance difference advances further is when multiple units are installed in an array. An optimized, modulated sequence of an array can take advantage of the aperiodic, asymmetric shape of the Modviewsor™ to minimize lobing effects that are caused by symmetrical and periodic shapes. In contrast to a Diviewsor® periodic array, a Modviewsor™ aperiodic array is formed by following the prescription of an optimal binary sequence, which indicates when to use the asymmetric base shape (zero) or the rotated unit (one). The Modviewsor™ is available in clear, translucent, tinted and higher opacity acrylic surfaces. It is sized to fit into a standard, reinforced T-Bar grid; more often, it is framed into a wall or ceiling in a fashion similar to mounting a glass panel.
Problem
Interfering reflections that degrade speech intelligibility, gain before feedback, and music quality can be controlled by absorption and/or diffusion. When absorption alone is used to control reflections it creates "dead" sounding spaces that lack the benefit of late order, high frequency reflections which can greatly enhance the acoustic performance of a space. When performance spaces require glass surfaces for viewing, day lighting or special lighting effects, conventional high opacity materials that most diffusers are made out of are not plausible solutions.
Solution
To solve this problem, RPG developed a new light transmitting, optimized sound diffuser called the Modviewsor™. The Modviewsor™ embodies two patents; Shape Optimization and Aperiodic Modulation of a Single Asymmetric Base Shape. The optimized, asymmetric base shape of the Modffusor™ consists of 7 full wells and two zero-depth, half wells on either end. This optimized asymmetric surface is now capable of being arrayed in an aperiodic manner, using optimal binary sequences. This offers a significant performance advance over conventional designs.
