RPG Gives Back: CHRG
To provide continued support to the acoustical community, RPG has sponsored a student scholarship for the Concert Hall Research Group Santa Fe Summer Institute. Press coverage can also be found in the New York Times and CNN following the July 25-29, 2010 event.

Topperfo Graphic: Quiet Beauty!
Topperfo Graphic helps architects express themselves. In collaboration with architects around the world, Topakustik is introducing exciting standard and custom graphic designs on painted or veneered panels, offering sound absorption to quiet noise and excessive reverberation, while offering striking visual designs. The image shows a back-lit floral graphic in a restaurant, but you can express yourself by providing a dxf file of your logo or custom graphic. You no longer have to sacrifice design to provide a comfortable acoustical environment to either improve speech intelligibility or enhance music appreciation.

Microsorber Solution for Radiant Ceilings
Radiant ceilings offer an energy efficient way to cool and heat a room uniformly, and are gaining acceptance and applications. However, from an acoustical perspective, untreated thermally active ceilings create an overly reverberant space. Since absorptive materials cannot be placed directly on the radiant surface, sometimes vertically hanging baffles are suspended from the ceiling. This could be intrusive. A new microperferated foil offers the option of being installed parallel to and spaced below the surface in a single or double layer. The foil can be transparent or translucent, as shown, to allow lighting to be placed above it. The application allows for air movement and does not interfere with the thermal efficiency, while offering a comfortable environment.

Engineering a quieter world The CDM Noise and Vibration system addresses all aspects of noise and vibration, including isolating subway and surface rail vibrations, floating entire buildings or decoupling structural elements, isolating performance spaces, recording and broadcast facilities, residences, home theaters, sports and fitness facilities, physical plants and mechanical rooms, elevators and much more.
