Abstract
A panel which diffuses sound incident thereupon is provided having a rectangular perimeter and wedge-shaped configuration wherein the front surface of the panel is angularly disposed with respect to its flat rear surface. The front surface contains a series of parallel elongated depressions. A multitude of such panels are employed along with sound reflecting and sound absorbing panels to produce a wall-mounted assemblage of sound-interactive panels capable of desirably modifying the subjectively perceived quality of sound in a room or auditorium.
Claims17
A sound-diffuser panel having:
- a) a flat rear surface,
- b) opposed parallel first and second long side surfaces and opposed parallel first and second short end surfaces, said side and end surfaces being forwardly directed from said rear surface to constitute a rectangular perimeter and terminating in straight forward edges that lie in a front plane inclined with respect to said rear surface, thereby causing said panel to have a wedge shape characterized in having a plane of symmetry that bisects said side surfaces in orthogonal relationship to said rear surface,
- c) a front surface comprised of:
- 1) a series of parallel flat lanes extending between said end surfaces and disposed within said inclined front plane, and
- 2) elongated recesses disposed between said lanes, and
- d) an interior compartment bounded by said front, rear, side and end surfaces,
- e) said several surfaces being comprised of plastic sheet material having a thickness between {fraction (1/16)} and ¼ inch.
