Sound masking comes in several varieties. The biggest difference in
systems is the speaker location. Some systems use speakers that point
down into the workplace (direct-field). These systems will provide improved privacy
in the area but they will not provide uniform sound coverage. They are
also very noticeable (especially to tall people) as one walks around
the space. Downward facing speakers also must be placed around lights,
HVAC components and other ceiling features.
Plenum speakers are located above the acoustical ceiling and are
pointed up. The sound bounces around above the ceiling and filters
down through the ceiling uniformly.
We think this works better and is more acceptable to the occupants of the office. We have removed several direct-field systems and replaced them with plenum based systems.
Of course in areas without acoustical ceilings, the sound can be
delivered from attractive speakers (also pointed up) suspended from the
structure. We also frequently locate speakers under raised access
floor.
There are other key differences in systems. Give us call and we can make it easy to understand.
