Acoustic device for wall mounting for diffusion and absorption of sound
First Claim
1. A wall-mountable acoustic device for diffusion and absorption of sound in an indoor area, comprising:
- a) a self-supporting mat of compacted and interbonded rockwool fibers, said mat linearly elongated between opposite end extremities and bounded by
1) a convex exterior surface of circular cylindric shape extending 180°
in circular curvature,
2) a concave interior surface substantially concentric with said exterior surface and extending 180°
in circular curvature,
3) two diametrically opposed straight flat rear surfaces in parallel and coplanar juxtaposition, having identical widths which represent the thickness of the mat as measured orthogonally between said interior and exterior surfaces, and
4) opposed flat end surfaces having a semicircular perimeter,b) a thin facing material tautly embracing said exterior surface and extending across said rear surfaces and onto said interior surface, andc) an end panel of flat contour disposed upon each end surface and extending between said exterior surface and rear surfaces, and having a back surface disposed in substantially coplanar relationship with said rear surfaces and in a rectangular configuration therewith, whereby,d) when said device is mounted upon a wall by way of abutment with said rear and back surfaces, said mat, end panels and wall define a fully enclosed internal chamber of semi-cylindrical configuration.

Abstract
A wall-mountable acoustic device for absorption of sound in an indoor area is constructed of self-supporting interbonded rockwool mat material. The primary component made of the mat material is shaped in semi-cylindrical configuration. End panels of rockwool mat of similar composition are attached to the opposite ends of the semi-cylindrical configuration to enclose the configuration except for an open rear extremity of rectangular perimeter. When attached to a flat wall, a totally enclosed semi-cylindrical chamber is defined. In a preferred embodiment, further improvement of sound absorption properties is achieved by way of a diaphragm disposed within the semi-cylindrical configuration.
