Small rooms like Project Studios need a very
efficient surface to diffuse interfering rear wall reflections and provide a diffuse sound field.
To solve this problem, RPG® utilized advanced primitive root number theory to design the most powerful and aesthetic two dimensional omnidirectional diffusing surface in the acoustical industry.
Interfering reflections can be controlled by absorption or diffusion. In small rooms, it is often desirable to control interfering reflections and provide an ambient sound field using diffusion instead of absorption. When the room’s surfaces are relatively close to the listener, a very efficient diffusing surface is needed. To solve this problem, RPG® patented the Skyline®. It is the industry’s first — and most efficient — omnidirectional primitive root number theory two dimensional diffusor. The Skyline® scatters incident sound uniformly so that the acoustic glare in all directions is minimized.
The solid expanded polystyrene core of the Skyline® provides useful low frequency absorption.
The uniformity of diffusion is characterized by the standard deviation of the 1/3 octave polar response, for a given angle of incidence. For each of the 37 angles of incidence, 37 backscattering impulse response measurements are made at 5° increments between 0° and 180°. The Diffusion Coefficient is the mean standard deviation for all angles of incidence, normalized to the standard deviation of a delta function (1 equals ideal diffusion). The data illustrate the exceptional uniformity of diffusion above the diffraction limit (565 Hz = 1130 ft/sec/2'), which is related to the 2' dimension of the panel. The Diffusion Coefficient of a flat reflective panel is shown for comparison.
Patented optimized primitive root reflection phase grating
156 distinct phase blocks
Suppressed specular scattering
Universal mounting design
Portable, lightweight construction
Unique acoustic sculpture
The large prime number design offers the acoustical industry's highest reflection density. This design provides a natural sounding ambiance and the most effective diffusive control of interfering reflections
The specular suppression afforded by the primitive root number theory design means the "mirror" reflection component of the scattering is reduced creating a more diffuse sound field
The Skyline® is very easy to install on walls or ceilings
For permanent mounting you may wish to also apply construction adhesive. Skylines® can also be inserted into a T-bar ceiling grid.
