摘要：
In accordance with an embodiment of the invention, a sound masking system is used to produce a sound masking zone in the vicinity of a defined area, for example in an area surrounding a conference room, an area within a medical office, or an area within a place of worship. A screen of loudspeakers around the defined area is used to create the sound masking zone. An indicator light, outside the defined area and unique to the sound masking zone around the defined area, is used to indicate that the sound masking system is active or ramping up.
