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.
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® utilized advanced primitive root number
theory to design the most powerful and aesthetic two dimensional
omnidirectional diffusing surface in the acoustical industry.
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
Absorption
The solid expanded polystyrene
core of the Skyline® provides useful low frequency absorption.
Installation
The Skyline® is very easy to install on walls or ceilings using
either construction adhesive or the supplied hook and loop fasteners.
Apply both sides of the hook and loop fastener to the rear of
the Skyline® in each corner on a flat area. Remove the protective
paper from the exposed side and apply to the wall. For permanent
mounting you may wish to also apply construction adhesive along
with the hook and loop. Skylines® can also be inserted into a
T-bar ceiling grid. Be sure to apply all Skylines® in the same
orientation.
WARNING:
The Skyline® is fabricated from flame- retardant, high- density
expanded polystyrene foam. It is the nature of this material to
have rough surface imperfections and contain steam vent holes.
Some of these imperfections can be partially concealed by a factory
paint process. If you are interested in a painted product, RPG®
offers a painted version in Duron Multispec Fine Fleck paint.
RPG® does not recommend that the Skyline® be painted in the field
and assumes no responsibility for any damage resulting from field
painting.
