Abstract
The invention involves the use of a plurality of incoherent noise generators distributed, in one embodiment, along ceilings in open-plan and partitioned office spaces and the like, to diffuse masking sound energy through acoustical tile and other false ceiling structures while tailoring the same for speech privacy results, by providing a uniform, delocalized and incoherent masking sound space.
