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
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, construction adhesive
must also be applied, where space allows on the back of the unit, along
with the hook and loop fasteners. The Skyline® can also
be inserted
into a T-bar ceiling grid.
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.

Skyline®
The First Two Dimensional Primitive Root Diffusor From The Acoustical
Industry’s Leading Innovator
The Skyline®
has received a 1999 Golden Ear Award from The
Absolute Sound. Skylines® "add both focus and bloom, and without
shortening reverb time or rolling off high frequencies."
| Features
& Benefits |
Features
Patented optimized primitive root reflection phase grating
156 distinct phase blocks
Suppressed specular scattering
Universal mounting design
Portable, lightweight construction
Unique acoustic sculpture
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
The lightweight and universal Skyline® design with perimeter
flange permits mounting on a wall, ceiling, or free standing
portable gobo partitions with hook and loop fasteners or in
a T-bar suspended ceiling grid
The complex number theory topology allows one to work closer
to a wall surface than would normally be the case. Thus, small
edit and recording control rooms can be optimized
The Skyline®'s unique sculptured topology makes it a welcome
aesthetic addition to the decor of the room |
