Sound masking is the use of embedded sound in an environment for the purposes of interrupting, or masking, other external sounds. Sound masking is useful for several scenarios, such as offices, public places, even outdoor spaces. Sound masking systems have developed to an advanced degree that they now cater to a specialized set of needs.

In setting up sound masking systems, we have to study the architecture to be masked to verify what spots can be installed in. Usually, speakers are placed above the ceiling so that the sound would be evenly distributed. Alternately, they can be placed out of plain sight in secret hiding places, or elaborately buried.

In the office, sound masking systems are used to inhibit gossip, loud talking, eating sounds, radio or other music sources, and other audible distractions. This is also done to make sure personal conversations aren't easily interrupted, overall improving productivity. How important is office privacy? You may be required by law, as there are regulations that demand privacy control in offices.

On a personal level, sound masking systems will inhibit surveillance systems from monitoring you, so that you can feel safe around your home and property. And they can be used to give outdoor environments their natural atmosphere back. This is useful when the ambiance of the area in question is interrupted by neighboring houses, factories, commercial establishments and the like.

Different manufacturers make different sound masking technologies. If anything, the one thing they have in common among them is the production of masking sound at a specific decibel. This sound should be just enough to inhibit sound on the level of human speech. On the other hand, it has to be low enough that it does not alert the ear.

When looking for a sound masking system, your inquiry should cover the technology and not just the brand name. You'll also want to inquire about the sound masking related services these companies provide. You may want to look into active noise control, which is a viable alternative in itself. Some environments, such as airports, use and in fact need both systems as sound control solutions for different concerns.
