Background:
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 characterisation 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. |
Installation:
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.
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.

Performance:
Its scattering features improve with the application of more modules.
The DYNAMICFLOW Ac Sh® is a large-sized diffuser that provides a very homogeneous diffusion within the sound and diffuse spectrum (link for the dynamicflow® features).
In order to determine the “scattering coefficient”, simulations were carried out on raytracing during the method to develop the product (link for video scattering). |
