Abstract: A sound masking system includes a self-amplified loudspeaker emitter unit, with a driver and enlarged ported enclosure, sufficient to provide a frequency range down to a low frequency, such as about 125 Hz. To deliver the power, the power distribution architecture includes audio power amplifiers in the emitter housing of each loudspeaker. Raw power is delivered to each emitter unit through a cable and connectors, such as an Ethernet cable and connectors, in the same cable with the sound masking and audio signals. Inside the emitter units are electronics that efficiently convert the raw power and low level signal to drive the loudspeaker directly. The power comes from a typical desktop power supply, from which the power is combined with the sound masking and audio signals using a power injector unit that distributes the combined power and signals to loudspeakers. The loudspeakers can connect to an individually addressed sound masking network.

Abstract: 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.

Abstract: A modular housing assembly is provided for two incompatible circuits, for example an RF circuit and a digital circuit, mounted on the same printed circuit board. The housing assembly has a base member and a cover member which are meshed to form two double walled compartments separated by a double conducting wall. The circuit board has at least one bridge physically and electrically connecting the two cicuits on the board which bridges pass through corresponding channels in the separating wall and each contain a matrix of plated through holes which operate to extend the wall through the bridge. Interconnecting wiring is woven through the holes to pass desired signals. Filters are provided between the interconnecting wiring and each circuit to eliminate conductive interference. Conductive gaskets are provided at all junctions of the separating wall with a housing member or with a circuit board to further reduce radiation leakage between the circuits.
