PORTABLE DIFFUSION ACOUSTIC SHELLS

DYNAMICFLOW®AcSh® • WOODFOIL® AcSh® • PLURA®AcSh®

WOODFOIL® AcSh® DESCRIPTION

WFLAS4 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
DYNAMICFLOW® AcSh® PLURA® AcSh® diffuser.
Therefore, we are presenting new design proposals that are less common in diffusion
DYNAS4 PLRAS4 structures designed for mobile use.
The DYNAMICFLOW® AcSh®, the WOODFOIL® AcSh® and the PLURA® AcSh® are an easy-
to-install portable acoustic diffusion shells meant to be used in certain types of musical PORTABLE DIFFUSION ACOUSTIC SHELLS | DIFFUSION ACOUSTIC SHELLS
concer ts.
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.

MAIN FEATURES

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 DYNAMICFLOW® AcSh®, the WOODFOIL® AcSh® and the PLURA® AcSh® are a large-
sized diffusers that provides a very homogeneous diffusion within the sound and diffuse
spectrum.

DIFFUSION WITH SCATTERING EFFECTS

It emphasizes the sound diffusion at a wider covering angle, effective at a shorter
incidence distance.

Features: efficient at a shorter distance; less sound level; wider incidence angle.
