Problem
Small rooms like project studios need a very
efficient surface to diffuse interfering rear wall reflections and
provide a diffuse sound field.
Solution
To solve this problem, RPG utilised 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.
Absorption
The solid expanded polystyrene core of the Skyline provides
useful low frequency absorption.
Diffusion
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.
Features
Benefits
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.
Installation
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.
