JOCAVI® has developed this acoustic diffusion panel by using non-linear convex shapes, based on a set of three ellipses which were later altered and optimised in order to achieve an oval shape with better angular diffusion coverage. 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 DYNAMICFLOW®’s interior is composed of a substance made of impregnated mineral fibres and textiles, which gives this product a specific mass and also contributes to its consistence.
FEATURES
Manufactured with ABS. Average diffusion: 0.61/m2 [>100Hz;<5KHz] Fire-resistance: M1 100% recyclable Installation: accessories included
DYNAMICFLOW® AcSh® removable acoustic shells are composed of four 120cm x 120cm modules which are set on a flight-case type box. This box is part of the basic structure of the shell itself and there is no need to store the box while the shell is being used. Two people are enough to install it on the stage floor.
This shell adapts to each orchestra according to the number of musicians, groups of instruments and the stage area by adjusting the quantity of modules to be used. It is versatile since it allows several configurations in accordance with the musical formation, as well as the easy access of musicians and instruments and a quick assembly and disassembly.
This shell is easily carried on its wheeled box. When not in use ,it is kept in storage in order not to interfere with the good functioning of the performance room.
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® are a large-sized
diffusers that provides a very homogeneous diffusion within the sound and diffuse
spectrum.
SPECIFICATIONS
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 DYNAMICFLOW® 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.

PERFORMANCE
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.
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.
In order to determine the scattering coefficient, simulations were carried out on ray tracing during the method to develop the product.
Diffusion with scattering effect
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.
