A two-dimensional sound diffusor is composed of a plurality of wells defined by a matrix of projecting elements. The wells, which have different depths and widths, are arranged in a repeating pattern. The boundaries of the wells and of the repeating pattern are defined by projections arranged on a base. The ends of the projections extend away from the base, terminating in an inclined face which is inclined relative to the base by an angle of 10 DEG . The incline may be rotated from one projection to the next, on a plane parallel to the base of the unit by 90 DEG or 180 DEG . This arrangement produces two dimensional sound diffusion.
