RPG effusor Newsletter - June 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.

RPG Waveform Gaussian Specified at WNYC
RPG is proud to have contributed its Waveform Gaussian Wooden surfaces to form the acoustical shell in the recently completed Jerome L. Greene Performance Space. The nation’s most listened-to public radio station, WNYC, now enters a new dimension with the opening of The Jerome L. Greene Performance Space. A new destination for the city’s incomparable arts and culture scene, The Greene Space is a state-of-the-art, multimedia performance space and broadcast studio on the ground floor of WNYC’s new home, 44 Charlton Street (at Varick Street).

RPG DiffusorBlox at Zanesville Church of Christ
RPG DiffusorBlox were specified by dBA Acoustics Tom Lorenzen to control the acoustics in the gymnasium. The block were pigmented to a colored band of diffusion in the upper walls for an aesthetic as well as an acoustical solution to controlling the sound.

RPG Topperfo at the Country Day School
RPG Topperfo 16/16/8 in white oak veneer was specified by Gideon Toal Architects and installed in the dining facility of the Country Day School, Forth Worth, TX by Marek Brothers. Topperfo was mounted in a modified T-bar grid with trim. There are 3 floating ceiling areas with integrated lighting. Total area: ~4110 square feet. We invite you to visit the new Topakustik Website.
For more information on the Topakustik system or to request a new brochure, 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 for efficient sound isolation. Elastomers include natural rubbers, synthetic Neoprene rubbers, virgin and recycled cork-rubber elastomers, polyurethane and other foams, recycled tires and a complete range of springs with resonant frequencies down to 2.5 Hz. The system included easy to use floor, wall and ceiling isolators to effectively isolate interfering air borne and vibrational interference. 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.
