Abstract: Systems, apparatuses, and methods for diffusing sound can comprise a sound or acoustic diffuser or a plurality of sound or acoustic diffusers. The acoustic diffuser can be provided as a 90 degree segment to fit into an inside corner, and a plurality of 90 degree segments can be arranged relative to each other to effectively provide 180 degree, 270 degree, or 360 degree contiguous acoustic diffusers, where the 180 degree acoustic diffuser can be arranged relative to a flat wall, and the 270 degree acoustic diffuser can be arranged relative to an outside corner. Furthermore, each 90 degree segment, or contiguous combination of segments, can have vertically stacked thereon (or be vertically stacked on) another segment of same construction, in freestanding fashion.

Abstract: A device including a membrane having first and second faces; a first substrate disposed on the first face of the membrane and having (i) a plurality of first absorptive regions and (ii) a plurality of first reflective regions formed as wells in a face of the first substrate, the first absorptive regions and the first reflective regions arranged in a pre-defined grid pattern; a second substrate disposed on the second face of the membrane and having (i) a plurality of second absorptive regions and (ii) a plurality of second reflective regions formed as second wells in a face of the second substrate, the second absorptive regions and the second reflective regions arranged in the pre-defined grid pattern.
