Increase acoustical privacy in open workspaces and between enclosed spaces.
The design of a sound masking system should consider the following for even dispersion across a given zone: sound masking should be evenly spaced, either in a 30- or 60-degree offset, at a distance proportional to the ceiling height and plenum depth; sound masking ideally locates away from building structures and serves the centermost area of the space for the most even coverage; sound masking speakers can be plenum suspended, exposed, directly mounted or beneath raised access floors for best results. The sound emitted by a sound masking system resembles a combination of human speech and human hearing frequency content.
Sound masking is an effective method that, when installed and commissioned correctly, has the potential to bolster acoustical privacy in open workspace and enclosed office environments.
Implement Sound Masking (2 points)
Sound masking is provided in all of the following spaces and sound levels meet the following requirements when measured from the nearest workstation:
Open offices, libraries, cafeterias, corridors/hallways: 45 - 48 dBA.
Enclosed offices and quiet zones identified through S01: Sound Mapping, Part 3: Label Acoustic Zones: 40 - 42 dBA.
