DESCRIPTION TECHNICAL DRAWINGS

The MELLOWCLOUD® DIF is a One Dimensional Curved Shaped Diffuser Acoustic panel for 8 8
Multipurpose, Auditoriums and Theatre Halls. 180 200

This is a product was devised to be suspended in ceilings or metal grids; it can be also used as fixed or 100 120
motorized acoustic shells. This type of acoustic material is mainly applied in large area of application
such as auditoriums, conference rooms, multipurpose rooms and airports, places where acoustic MELLOWCLOUD® DIF | DIFFUSION PANEL
treatment with a modular continuous surface is required.

It is a diffuser material that also provides somewhat of homogenous sound spectrum absorption. The
MELLOWCLOUD® DIF evolves and meets the aesthetic challenge, while also offering an optimal sound
diffusion and absorption characteristics.

The architecture involves rectilinear and curvilinear lines. Flat rigid surfaces provide uneven sound
pressure across the audience area. Shaping and curving the surfaces can improve the coverage of the
sound diffusion; this will help the results, although it is a vast subject that requires its own tools of
experimentation on case-by-case base for each project. MELLOWCLOUD® DIF provides architects and
designers with wide latitude in curvilinear design.
MELLOWCLOUD® DIF can be customized as to its shape and size to better adapt to each space. Custom
panels offer in a variety of types, sizes, ellipses, geometric shapes, vaults, acoustical domes,
thicknesses, and finishes.
