AtlasIED M812-S2T7-BX-RS 8" Sound Masking Speaker with 70V Transformer & Channel Rail EnclosureOpen office plan designs are becoming increasingly popular. To maintain a successful acoustic environment in such areas, it is important to take into account the interacting variables which influence office privacy. All components must be coordinated: ceiling/wall treatments, furniture/ furnishings, and HVAC systems. In most cases, a sound masking system will also be required to achieve adequate speech privacy at normal voice levels. Masking systems aid in creating continuous background coverage by adding low level sound to obscure ambient noise. The intelligibility of surrounding speech is reduced, as well as the distraction from daily office activity noise.
The selection and placement of masking loudspeakers to control ambient sound is essential for achieving sound privacy in an open office environment; this is true for individual workspaces, as well as in common areas frequented by office workers (i.e., hallways and lounges). Without similar sound levels in both, the workspace could be perceived as noisy. In areas where accurate speech communication is necessary (i.e., conference or meeting rooms), masking is not recommended.
This model is specifically designed for use in T-Bar support systems and is ideal for shallow ceiling applications. Because the loudspeaker is situated as close to the T-Bar as possible, the remaining area enables maximum sound dispersion. Additional units may be required in the following instances: the transmission loss of ceiling panels is low; the distance between the tiles and soffit deck is shallow; the area is occupied by equipment (i.e., HVAC equipment); and if the workspace below has a lower ceiling and small cubicles.
Model allows upward sound dispersion and includes two 23-3/4" (603mm) channel support rails and the necessary hardware for installation in T-Bar ceilings. Heavy-gauge CRS enclosure is acoustically treated with undercoating and 11/2 lb./cubic foot density fiberglass to absorb the resonance associated with high-frequency sound transmission. Unit is finished in black epoxy.
Factory-mounted and wired 70.7V (T7) transformer is supplied with 0.5, 1, 2, and 5 watt primary taps. Taps are externally accessible to facilitate power selection without dismantling the assembly.
Model enclosure offers a cubic content of 529 cu. inches C10A, 8" Diameter loudspeaker and a 70.7V (T7) transformer. Loudspeaker mounting plate contains no perforated grille and thus positions the speaker cone as fully exposed
