I want to take this opportunity to thank the acoustical consulting community for the wonderful support and encouragement you have given me and the trust you have placed in RPG. You are important to us and we are striving to provide you with an ever expanding palette of AcousticTools®. We have increased our architectural representation in many areas to provide consultants with a local presence. If you do not know who your RPG rep is, it shouldn’t be long before he is soaking up your billable hours. RPG is continuing to push the acoustical envelope with CHAOS™ and other innovative optimization and auralization software, but we are now also systematically trying to acoustically enhance and evolve traditional products, like the fabric wrapped panel, the pyramid, convex arc, drapery, perforated panels and the Helmholtz absorber. Our new compression molded Golden Pyramid™ is based on the aesthetically pleasing golden mean and comes in matching absorptive and diffusive versions. We also morphed the fabric wrapped panel into a turbo charged Binary Amplitude Diffsorber™. When you think of specifying a fabric wrapped panel, it will be too BAD™ if you don’t consider the benefits and economy of the Binary Amplitude Diffsorber™. In an effort to provide product brochures in a timely manner, we have taken all graphic design in house. Consultants should be receiving printed information and samples on a regular basis. Dr. Peter D’Antonio Featured Products: Golden Pyramid The pyramid continues to be a popular geometrical shape. To introduce a bit of mathematics and aesthetics, we have developed an asymmetrical pyramid based on the golden mean, which occurs in almost every aspect of our lives. To expand the pyramid’s uses, we compression mold the pyramid out of fiberglass at two densities. For absorbing applications, we apply a non bridging flec paint finish to a 7 pcf molded pyramid. For diffusing applications, we apply a resin and paint finish to a 21 pcf molded pyramid. This approach offers color coordinated, matching absorptive and diffusive panels at the lowest cost in the industry. BAD™ Panel We knew consultants were looking for an alternative to the conventional fabric wrapped panel, but we never expected this level of interest and excitement! The test data are equally exciting. Scattered sound above 1kHz is uniformly distributed by the binary amplitude grating surface and energy below that frequency is absorbed. This means we can offer a flat Diffsorber™, which provides low to mid frequency absorption and high frequency diffusion. The BAD™ panel is available as an upholstered panel or as a core material for stretch fabric systems. Room Optimizer™ We are very excited about RPG’s first software release called the Room Optimizer™. It seems like this is one of those AcousticTools® consultants have been wanting for years. Comments and orders at the Los Angeles NAMM show were very gratifying. The program contains room configuration wizards for stereo and the various 5.1 multi channel music and home theater formats. Also, it can handle any loudspeaker type. Simply input the room dimensions, loudspeaker information, search limits, and the program automatically determines the best positions for listener and loudspeakers that produce the flattest room response. An upgrade path from rectangular rooms to any shape room is planned, including auralization. |
