JOCAVI USA CORP www.jocaviusa.com | [email protected] DIFFUSION PANEL NATURAL WOOD Image of 60x60cm model Ref.:WGL060(on the left) and the same model applied (closeup image). TECHNICAL DRAWINGS DESCRIPTION The use of solid wood in the construction of acoustic diffusers is a very classic custom in studio design. The use of diffusers is imperative to control primary reflections and other reflections from the flat surfaces, improving correct sound diffusion to the listening position. JOCAVI® designed this model with a dual sequence function comparing with the conventional quadratic diffusers, that is, it has two residual quadratic routine calculations, one regular and one inverted. The usual square gives way to two triangles in the same square. As a result, WOODGLEAM® has two triangles with different depths with the main sequence and the inverse sequence, within one square. The WOODGLEAM® is a two-dimensional dual routine quadratic residue sound diffuser created to provide a more uniform sound field through the reflection of the mid-range frequencies. It offers a dual hemispherical scattering for shorter angles of incidence, which is an advantage for small and medium-sized rooms.This wooden diffusion panel can be combined with its similar WOODQUAD® which has simple quadratic calculus, and has the uniform scattering properties of a regular quadratic diffuser. This panel is made of solid pinewood with a finish of several different colors makes this product look very attractive, both acoustically and aesthetically.
