The diffusing acoustic shells are acoustic treatment elements intended for large volume rooms, such as theatres or auditoriums with a stage where orchestral concerts or mere recitals take place. These acoustic diffusing components are meant to project the nonamplified original sound from the stage to the audience. This will enable people to hear the sound coming directly from its sound sources and instruments, without the electro-acoustic inherent characterization or colouring. This panel also aims to enable the stage and the room to be within the same space and not separate in two by the mouth of the stage. JOCAVI’s models have been designed at the specific scale of these needs. Due to its shape and depth, they also have a high diffusion coefficient on medium/low frequencies. The all are large-sized diffusers that provide a very homogeneous diffusion within the diffuse and sound spectrum.
Manufactured in HIPS with a rigid framework, these pieces can be coupled and multiplied in order to suit each project’s demands. When mounted, several modules should be grouped so as to obtain an area that is proportional to each space.
Mounting: They can be hung from the ceiling in a strategic position in order to obtain sound diffusion in the required angles. They can also be mounted with a motorized rigging system from the stage ceiling. These elements / modules are fastened with steel cables by using appropriate mounting accessories. Their low weight makes mounting easier. As with any other JOCAVI diffusion panel, these models can also be applied on false ceilings, flat ceilings or walls.
Fixed acoustic shells come in lateral, background and ceiling modules. These allow various angulations to be defined according to the degrees of incidence towards the audience.
These modules are suspended above the stage using aluminium and steel cables. They may be moved manually or using a system electric engines where the most common positions can be pre-programmed.
When not in use, the shells can be placed together completely inconspicuously.

Two diffusion effects: by scattering in a wide radius or by compression in a narrower radius.
To adjust the diffusing properties of these models to the room where this product is applied, the placement of the pieces must be taken into account in order to obtain its best performance, bearing in mind these two types of diffusion:

It emphasizes the sound diffusion with a smaller covering angle, effective at a longer incidence distance.
Features: efficient at a longer distance; smaller incidence angle; higher sound level.

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.
