RPG effusor Newsletter - May 2009

RPG Continually Evolving
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.

We invite you to visit the new fiber-free, light-transmitting, microslit Clearsorber Deamp website to find out how to get absorption with a view.

Announcing The New Topakustik Brochure and Website
We are proud to announce the new Topakustik Brochure and Website and invite you to learn about the industry's widest selection of perforated, grooved, microperforated and graphic acoustical options, plank and panel options, wall and ceiling suspension options and the finished projects are beautiful to behold and audition. For more information please contact Sarah Brown, Director of Architectural Acoustic Sales, at sbrown@rpginc.com or your nearest representative.

RPG Waveform at the Picotte Recital Hall
The Massry Center for the Arts, designed by Saratoga Associates of Saratoga Springs, NY and built by Sano-Rubin Construction of Albany, NY, is a new showcase for music and the visual arts at The College of Saint Rose. The Kathleen McManus Picotte Recital Hall has a volume of 126,000 cf. The band/orchestra rehearsal rooms are directly above the recital hall. The designed STC 95 and IIC 82 separation between the spaces makes concurrent use possible. Read More.
For more information on the complete Waveform system, contact Sarah Brown, Director of Architectural Acoustic Sales, at sbrown@rpginc.com or your nearest representative.

Announcing the Waveform Biradial at Ladore
RPG is proud to announce the new 8'x8' Biradial, which is a GRG panel curved in two orthogonal directions. The units are ideal for large spaces with high ceilings, where they provide omnidirectional scattering and have an appropriate aspect ratio. The units are shipped in four 4'x4' section, which bolt together and are suspended from embedded metal loops with metal cable. For more information please contact Sarah Brown, Director of Architectural Acoustic Sales, at sbrown@rpginc.com or your nearest representative.



New CDM Binder Now Available on Request
The CDM Box-in-Box isolation system offers the widest range of elastomers with the lowest resonant frequencies and springs resonant frequencies down to 2.5 Hz. We invite you to review the features and benefits of this new system. For more information about the complete floor, wall and ceiling isolation system, please contact Tom Ryan, Director of Noise and Vibration Sales, at tryan@rpginc.com and request a new binder and samples.

CATT
We continue to offer assistance with the most comprehensive acoustic modeling and auralization package, CATT-Acoustic v8.x. and provide absorption and scattering modeling coefficients in CATT and EASE formats. New pricing effective 11/1/2007. Prediction and Auralization modules each $3,000. We can help facilitate the building and prediction of your models.

Education
Please join us for our Diffuse Seminars. Dates to be announced. You can view the Agenda pdfs on line. We also invite you to visit our Acoustics Library, Diffuse Reflections, Diffuse Bulletins and Competitive Evaluations.

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 (shown below) 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.
