Sound masking system

摘要

Disclosed is a sound masking system including an airflow unit housing at least one speaker generating a masking sound field. The airflow unit is often an air diffuser set into a conventional suspended ceiling comprised of ceiling tiles. The air diffuser provides an acoustic hole in the ceiling plane whereby sound can travel into the room unencumbered by the plane of ceiling tiles. The speaker is housed within the air diffuser and is directed into the room to be treated. The speaker is capable of producing sound waves in a frequency that masks the human voice.
