RPG WAVEFORM GAUSSIAN W

Product Description

Classical architecture benefitted from the fact that wall and ceiling surfaces contained texture in the form of relief ornamentation, coffered ceilings, etc. In addition to being beautiful these surfaces provided sound scattering which improved the acoustics of these spaces. Modern architecture is devoid of these sound diffusing surfaces and typicall contain flat reflecting surfaces which do not scatter sound, but rather redirect sound, like a mirror reflects light. RPG has developed a series of diffusing surfaces, called Waveform™, which complement contemporary architecture, in the way textured surfaces complemented classic architecture. One of these Waveform™ surfaces is called the Gaussian, because its shape resembles the classic gaussian probability curve. Many of the optimized Waveform™ surfaces, like the Spline and Bicubic, are asymmetric and aperiodic modulation is possible by installing the unit in its base shape or rotated 180 degrees. The Gaussian is symmetrical and thus we offer it in two depths, so that the units can be aperiodically modulated for optimal performance.

Problem
Flat surfaces on walls and ceilings provide uneven sound pressure levels. Coverage can be improved by curving or shaping the panels, but there is no guarantee that optimum results will be obtained and consequently uneven response is often experienced.

Solution
To solve this problem, RPG developed the first Shape Optimization™ program, which automatically determines the best shape and array of curve optimized surfaces to insure uniform coverage. The Shape Optimizer™ combines the power of the boundary element and multi-dimensional optimization techniques, incorporating the diffusion coefficient as the metric of optimal performance. The aperiodically mounted Waveform™ Gaussian shapes provide optimal ensemble for musicians on stage and uniform coverage in the audience.

Diffusion
AcousDataThe random incidence acoustical data illustrates how the Waveform™ Gaussian W provides useful sound diffusion in the lower midrange through the higher frequency range. The chart displays the random incidence diffusion coefficient, as determined according to AES-4id-2001 from the autocorrelation of the 1/3 octave polar responses for incidence angles of 0, +/-30 and +/-60 degrees, the correlation scattering coefficient for computer modeling calculations and the A-mount absorption coefficient for reference.

Installation
For ceiling suspension, a metal thimble is provided to capture a wire cable through the holes provided in the ribs at the rear of the panel. For wall mounting, a wooden cleat is provided.
