Golden Pyramid
The First Pyramid Based on the Golden Mean
From The Acoustical Industry's Leading Innovator |
Pyramidal shaped ceiling units redirect portions of the incident sound energy into different .While redirection is not true diffusion ,the pyramidal shape offers a moderate amount of acoustic control, preventing excessive harshness and flutter and providing more uniform sound distribution. RPG Golden Pyramid has an offset center based on the geometric Golden Rule. This offset center provides both visual interest and better acoustic performance. Constructed of heavy, fiber reinforced gypsum, the RPG Golden Pyramid offers superior acoustic performance over the lightweight gel-coat replicas provided by other manufacturers .An added benefit the Class-A fire rating.

Problem and Solution |
Problem
Sound absorptive acoustic ceiling tile (ACT)is commonly overused in room where people need to understand speech or listen to music .A low-cost but effective ceiling treatment that prevents acoustics problems while simultaneously distributing sound to the far room is need.
Solution
To address this problem , RPG developed the Golden Pyramid fits easily into a standard, metal, T-bar, ceiling grid and is Class-A fire rated . Acoustically ,the Golden pyramid redistributes sound across the room, aiding uniform listening and preventing acoustic problems such as flutter with the floor below.

Absorption
The Fiber Reinforced Gypsum fabrication is rigid and non-diaphragmatic, as opposed to conventional thermoformed plastic pyramids. Therefore ,the Golden Pyramid exhibits very low absorption, as indicated, for a 4£ø4 unit in both A and E mounts and for a 2 x 2 unit in E mount.
|
Diffusion
The Golden Pyramid is essentially a redirector of sound ,as opposed to a reflection phase grating ,providing reflection from each triangular face. The graph illustrates the average different (1 is ideal)for all angles of incidence .Compared to a flat reflecting panel ,the Golden Pyramid maintains uniform diffusivity as a function of frequency ,above the diffraction? limit.

Installation
The Golden Pyramid can be suspended in a T-bar grid . Because of the asymmetrical golden mean shape, the units can be oriented in three way (inset right) forming a two dimensional scattering array. |
