RPG Continually Evolving
Happy New Year. The RPG monthly effusor Newsletter introduces new products and services and highlights recent projects. If you are receiving this Newsletter for the first time, here is a link to all previous issues online.
See if you can solve the new acoustic puzzler!

Denver Museum of Nature and Science Genghis Khan Exhibit
The Denver Museum of Nature & Science is the Rocky Mountain region’s leading resource for informal science education. A variety of exhibitions, programs, and activities help Museum visitors experience the natural wonders of Colorado, Earth, and the universe. RPG provided approximately 4000 square feet of the Topperfo absorptive wood system. Panels were configured with a 1.2 mm face perforation which provides excellent mid to low frequency absorption with very little impact on the panel’s uniform aesthetic. The panels were constructed from a Class A fire rated, no added formaldehyde, and Forest Stewardship Council (FSC) certified MDF core and veneered with FSC certified American Cherry veneer for a completely “green” installation. This renovation was designed by Klipp Architecture of Denver, Colorado.

For more information on the TopperfoR System, please review the online brochure.

Educational Opportunities from RPG
RPG will be increasing its educational offerings in the New Year for both architects and acousticians. The AIA/CES accredited presentation has been updated with emphasis on product applications, finishes and installation. The Acoustical Continuing Education (ACE) program has also been updated with follow up Workshops available in the field or via GoToMeeting. These GoToMeetings will be offered weekly and acousticians can choose from a published list of topics including Products Descriptions, Applications and Research. Special GoToMeeting requests are also available on a topic of the specifier's choosing. We look forward to this expanded collaboration and invite you to take advantage of it.

New Drywall Isolation Clip
There are many wall and ceiling drywall isolation clips on the market. However, they all contain four basic problems that have been solved by the new ISO-CDM-QRW and ISO-CDM-QRC scientifically engineered clips now available. We invite you to read a new white paper describing how RPG has solved the problems associated with traditional approaches using one clip for wall and ceiling loads, only neoprene elastomers, non-physical capture of the drywall hat channel and non-optimal elastomer compression.

George Washington University – Smith Center Renovation RPG is excited to announce the unveiling of the Topperfo Micro in plank format and its first installation at the GWU Smith Center in both the Colonials Club and the Athletic Director’s Club. This installation was part of Phase 2 of the renovation of this space and was recently opened to the public with the Freshman Convocation and the first Men’s Basketball Game. In both spaces the architect incorporated the Topperfo Micro Plank in a Teak veneer as the ceiling surface. The planks are suspended with a T-bar grid and special turning clips to support the planks. This provided the ability to have a monolithic wood ceiling which looks much like wood flooring. Both spaces have integrated lighting and speaker penetrations, and the ceiling also incorporates access panel areas that are nearly invisible. The architect on this project is Gensler, Washington, DC.

University of Oklahoma – Gaylord Hall College of Journalism and Mass Communications RPG Modffusor™ sound diffusers are featured in the new 180-seat auditorium at Gaylord Hall. The auditorium features custom stained Honduran Mahogany units on the side and rear walls. The Modffusor™ units are installed in an optimized, modulated pattern on the rear wall and the side walls, featuring a patchwork design offering 2-dimensional sound diffusion. The acoustician on this project was PMK Consultants and the architect Rees Associates, Inc. (Oklahoma City, OK). Professor Scott Hodgson wrote to PMK Consultants: "Congratulations! As someone "living" in the space you have created I must say it is a joy to come to work in the morning and enter this wonderful complex. Your team is well deserving of the honor. Thanks for everything!"

Other Important Items to Note
New Acoustic Puzzler

RPG introduces a new acoustical puzzle! The first response with the correct answer wins a free copy of Dr. D'Antonio's 2nd Edition of the reference book Acoustic Absorbers and Diffusers: Theory, Design and Application

Question: An isolation floor consisting of a layer of ¾” plywood (2.2 psf), 2 layers of 5/8” Durock (3.75 psf each), topped by another ¾” layer of plywood is supported by an orthogonal array of 2”x2”x2” elastomers separated by 16” in both directions. A live load of 61.5 psf is expected. What is the acoustic design load in psf and the design pressure in psi on each elastomer? Send your answer to pdantonio@rpginc.com

Education

RPG now offers virtual meetings every week. We invite you to take advantage of this free educational opportunity by requesting a 30 minute GoToMeeting from the Seminar Topics. We also offer accredited AIA/CES lunch time courses on "The Next Generation of Architectural Acoustic Finishes", "Innovative Solutions to Noise and Vibration Isolation" and "Modern School Acoustical Design and LEED" at your office by contacting RPG or a representative in your area.

Test Data
RPG is offering random and directional incidence diffusion, scattering and absorption coefficients for all of its products. Random and directional incidence diffusion coefficients and polar patterns (click here to view an example) indicate the uniformity of diffusion and can be used in CSI specifications and as a metric to compare potential diffusing surfaces. The random incidence absorption coefficient can be used in CSI specifications as a metric of absorption efficiency. The directional and random incidence scattering coefficients can be used in computer modeling programs, but not as a metric of diffusion uniformity.
