Comparing Sound Masking Systems - Direct Field and Plenum Based Systems

Sound Masking systems come in many shapes and sizes, and it can be difficult to decide upon the right system for your office environment. Over the next few blog posts we will be covering differing aspects of sound masking systems.

Choosing between Direct Field or Plenum Based sound masking systems

In a Direct Field system, sound masking speakers are pointed down, directly towards the targeted area. In most cases, this means the speakers are installed on the ceiling surface, broadcasting downward towards the office occupants. The speakers are generally a visible part of the ceiling, like a sprinkler system.

Plenum Based systems are installed behind acoustic ceiling tiles, or under the floor. The system is generally, though not always, invisible to occupants. The speakers in Plenum Based systems are installed pointing up, away from occupants, so that the sound masking signal can reflect off of the ceiling, walls, floor and other architectural features of the office.

Both field types provide increased privacy and reduced acoustical distractions. When deciding between the two types of systems, factors to consider would be: your office architecture, office size, aesthetics, and system cost. An acoustical consultant, such as CCR ASSOCIATES, will analyze the architecture of your office, and may recommend one or the other type of system, depending on the specific design of the office environment.
