ACOUSTICAL Research

Every RPG product begins its life through a dedication to fundamental acoustic research. Whether a surface is intended to absorb sound, diffuse sound or perhaps do both, the science behind the interaction between the sound and the surface guides our innovation. Our dedication to research produced the first commercially available sound diffuser and has led to dozens of patents and innovations.

ACOUSTICS & The Environment

At RPG, we strive for a sustainable approach to manufacturing by meeting present needs without compromising the future. We offer FSC ® certified wood products, ecologically friendly and recycled components where possible and strive for local component sourcing.

ACOUSTICAL Manufacturing

RPG manufactures the majority of its product lines at its 100,000 square foot facility in Passaic, NJ which houses state of the art computerized production, hand crafted assembly and custom finishing under one roof.

3

ACOUSTICAL Design

The design process at RPG maintains the goal of merging art with the science, bringing together form and function without compromising performance. Some of the approaches that have grounded the art in science at RPG include mathematical number theory, diffraction physics, fractal geometry, pulse code modulation, shape optimization combining boundary element and multi-dimensional minimization techniques, computer analysis and laboratory testing.

ACOUSTICAL Engineering

Each new product design must meet the performance and quality standards that RPG products are known for worldwide. RPG’s quality assurance program includes computer modeling, scale modeling, a battery of acoustical testing and evaluation, full scale proto - typing and construction review stages - every new product is expected to push the boundaries of excellence.

ACOUSTICAL Testing

Without proof of performance, an acoustical product is simply artwork, millwork, cabinetry or upholstery. No other company tests its products to the exacting standards that RPG does in order to provide transparency and documentation, giving the designer a complete specification for each product; Absorption (both random and normal incidence), Diffusion and Scattering Coefficients.

Clearsorber ™ Foil is best mounted under tension for clean lines and maximum transparency. The simplest and most cost effective tensioned mounting utilizes stainless steel grommets at each corner of a Foil panel which is captured by a spring and stretched to an attachment point (D-ring). A hem bar mounting is also available and is recommended when longer spans are required. The Foil can be mounted in a draped fashion across the ceiling (best performance) or incorporated into most roller blind assemblies for operable functionality.
