Sometimes referred to as a "White Noise System", a sound masking system emits low-level, non-distracting masking noise designed to reduce speech intelligibility and thereby improve speech privacy as well as improve on lowering the amount of distractive noises that reduce our concentration and productivity.
A typical sound masking (white noise) system consists of a masking noise generator, an equalizer, one or more power amplifiers and a group of special loudspeakers installed above a drop ceiling. Well designed room acoustics are an important component of a successful masking system.
The Economic Benefits of Sound Masking

The economic benefits of sound masking vary from application to application but can be very significant. Consider a large insurance company selling life insurance over the telephone. Many times each day, an agent will ask a prospective client for financial and health information. The insurance companies must maintain a reasonable degree of confidentiality for this kind of information. Yet, if the agents work in a traditional open office environment, the lack of speech privacy makes it nearly impossible to achieve this goal.
One way to provide speech privacy is to construct a private office for each agent. Not a low cost solution.
A lower cost solution is an open plan office with well designed acoustics and a sound masking system. This kind of environment can achieve normal speech privacy while maintaining the flexibility of the open plan office. As a side benefit, the masking also reduces unwanted distractions like office machinery and traffic enabling the office workers to maintain a higher degree of productivity.
