摘要： 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.

摘要： A sound masking system according to the invention is disclosed in which one or more sound masking loudspeaker assemblies are coupled to one or more electronic sound masking signal generators. The loudspeaker assemblies in the system of the invention have a low directivity index and preferably emit an acoustic sound masking signal that has a sound masking spectrum specifically designed to provide superior sound masking in an open plan office. Each of the plurality of loudspeaker assemblies is oriented to provide the acoustic sound masking signal in a direct path into the predetermined area in which masking sound is needed. In addition, the sound masking system of the invention can include a remote control function by which a user can select from a plurality of stored sets of information for providing from a recipient loudspeaker assembly an acoustic sound masking signal having a-selected sound masking spectrum.

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.

摘要： A wireless sound-emitting device includes a housing adapted to be coupled to a wall at a source of electric power, a loudspeaker positioned at a periphery of the housing, a control module outputting an electric audio signal to the at least one loudspeaker, and a wireless communications module in electrical communication with the control module. The loudspeaker emits acoustic signals in a direction parallel to the wall, when the housing is coupled to the wall, with the acoustic signals reflecting off the wall. The device may produce a sound masking noise or play a sound recorded on an internal memory. The device may include an electric plug or be adapted to replace an electric outlet faceplate. The device may have electric pass-through outlets and may be powered by the source of electric power. The device may be controlled remotely, for example via an Internet of Things (IoT) platform.
