How Does A Sound Masking System, Also Known As A “White Noise” System Work?

A Sound Masking System, also known as White Noise System, like white light, consists of all frequencies combined together.

White noise is a special type of sound signal which is used to mask background sounds, especially in open plan office areas.  When used to promote concentration, white noise helps to drown out sounds which might otherwise prevent you from focusing on the task at hand.

For another analogy let’s use light. Imagine using a flashlight in a dark room, as a result the light source will be immediately noticeable. But what if the room is already brightly lit? The flashlight is now barely noticeable because it has been “masked” by the brighter room lights.

How To Successfully Implement A Sound Masking System

Implementing the following technologies in your area will help improve your acoustics and increase the necessary private levels.

Absorption

Absorb sound waves by using high-NRC-rated ceiling tiles and acoustic wall panels, in addition to a sound masking system.

Blocking

Block by using high-STC-rated panels, partitions, walls, windows, etc, rather than traditional products.

Covering

Cover by adding an unstructured low-level background sound, also known as sound masking or white noise.

Conclusion

Most offices will require a combination of these three technologies to provide an acoustically pleasing environment. In most cases, no one technology by itself will solve your privacy needs. While covering provides the greatest increase in privacy per South African rand invested, it must be used in conjunction with a proper mixture of absorption and blocking in order to achieve specific privacy speech levels.
