PORTABLE DIFFUSION ACOUSTIC SHELLS | DIAMOND® AcSh® - DIA AS4

 

DESCRIPTION
 
DIAMOND® AcSh®
The Diamond® is a 3D-controlled dispersion multidirectional reflection panel with a depth factor that is logarithmically varied. It is, therefore, a three-dimension omnidirectional diffusion panel that controls primary reflections and fragments the energy in 64 vertices of incidence by using the theoretical numerical sequence ratio of the primitive root as a basis for calculation. It is built with ABS recyclable material, and its modular design makes it a particular and high-performance diffuser. The reflection angles were optimised according to mid-size room applications. The DIAMOND® is an acoustic diffusion element with a lozenge geometry. The front view refers to 64 interconnected polygons with four multiple sound diffusion angles, which determines a diamond shape. It was created in 16 singular modules that have a quadrangular base and different extrusion heights on each corner. The combination of those positions results in a geometrically scattering diffusion pattern with a very attractive shape. Thus, the DIAMOND® produces exceptional results of sound diffusion effect and provides spaces with considerable sound perception. Available in several colours..

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 DIAMOND® 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 Diamond® 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.
