PORTABLE DIFFUSION ACOUSTIC SHELLS | PLURA®AcSh®- PLRAS4

 

DESCRIPTION
 
Plura® AcSh® - PLRAS4

Plura® is an acoustic diffusion panel, manufactured in ABS on an absorbent filling box. Its design has a geometry that reproduces symmetry at a 180º rotation. It consists of a combination of two ellipses in one bent hollow, thus giving it a predominantly round shape with tenuous angles, which is good for diffusion. Plura® is meant to diffuse mid and mid-high frequencies. When using multiple pieces jointly on a continuous area, it improves its sound diffusion efficiency. Amazing diffusion effect can be obtained when used in large rooms. We can make several different aesthetic combination effects by rotating the panels 90º or 180º and positioning them according to one's taste and to the room’s requirements. The shape is the same as the Plura® ABL, which is an absorbent; they can be applied together to obtain different combinations of sound diffusion and absorption. The inner part of this model is made on a composite substance of impregnated mineral fibers and textiles, which gives this product a specific mass and also contributes to its consistence. The external raw material of this panel was selected out of some materials that have the fastest and most specific properties required for a diffuser with these characteristics, however the ABS still has some advantages, namely UV protection, impact resistance and fire resistance M1. The back part consists of a flat surface, which includes the mounting accessories. Its shape adjusts to even surfaces. Using our fastening materials we can apply it on walls and ceilings, “T” type mounting bars for false ceilings as well. This piece is available in various colors, thus allowing an appropriate background for each space. The mounting process is rather easy by simply using the fastening devices that are supplied.

Easy to install
Depending on the space available on the stage, more or less elements may be used in order to form the shape of a perfect shell. Built on a modular configuration with 120 x 120cm pieces, up to four modules can be coupled in height, thus totalling a diffusing homogeneous surface of 480 x 120cm. The PLURA® AcSh® are a large-sized diffusers that provides a very homogeneous diffusion within the sound and diffuse spectrum.

 

Based on works and experiments in the field of sound wave diffusion and the positive aspects that result from the presence of diffusers in rooms, we have built this acoustic diffuser. Therefore, we are presenting new design proposals that are less common in diffusion structures designed for mobile use. The PLURA® AcSh® are an easy-to-install portable acoustic diffusion shells meant to be used in certain types of musical concerts. It is a piece that changes the room's acoustics by enhancing its features. Diffusion shells are acoustic treatment elements used in large volume rooms, such as theatres and auditoriums. They may also be used outdoors for the performance of concerts by large orchestras or just recitals. The installation of these acoustic diffusion components is meant to project the non-amplified original sound from the stage towards the audience. This will enable to hear the sound that comes directly from the sound sources and instruments, without the characterization or colouring inherent to the use of electro-acoustics. These shells also enable the stage and the room to be within the same space and not separate in two by the mouth of the stage. These pieces do not need any preparation prior to their installation, just a free stage with good access. They must be coupled and multiplied in such a way that is adequate to each project in order to obtain a diffusing area that is proportionate to the space in question.
