SYSTEM AND METHOD FOR DEFINED AREA SOUND MASKING

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.

主权项

1. A sound masking system for providing a sound masking signal surrounding at least a portion of a defined area of a building, the system comprising:
a plurality of loudspeaker assemblies, each loudspeaker assembly coupled to one or more sources of an electrical sound signal, the electrical sound signal comprising a sound masking signal, wherein each of the plurality of loudspeaker assemblies is operative to emit an acoustic sound signal in response to the electrical sound signal, the acoustic sound signal comprising, during activation of a sound masking function of the sound masking system, an acoustic sound masking signal; wherein each of the plurality of loudspeaker assemblies is constructed and oriented to provide the acoustic sound signal to a zone surrounding the at least a portion of the defined area of the building; and an exterior indicator panel positioned outside the defined area of the building, configured to provide an exterior visual indication, during activation of the sound masking function of the sound masking system, that the acoustic sound masking signal is being emitted into the zone surrounding the at least a portion of the defined area of the building; wherein the exterior indicator panel is configured to provide the exterior visual indication uniquely for sound masking of the zone surrounding the at least a portion of the defined area of the building.
