Abstract
Methods and apparatuses for addressing open space noise are disclosed. In one example, a system and method for masking open space noise includes outputting a noise masking sound from a plurality of balanced mode radiator loudspeakers distributed in a down-fire direction above an open space.
Claims27
A system for masking open space noise comprising:
- a plurality of balanced mode radiator loudspeakers, each balanced mode radiator loudspeaker arranged above an open space in a down-fire configuration to output a speaker sound downward into the open space, and each balanced mode radiator loudspeaker comprising a voice coil, a diaphragm, and one or more mass objects coupled to the diaphragm;
- a display device disposed in the open space;
- and
- one or more computing devices comprising:
- one or more processors;
- one or more memories storing:
- one or more selectable noise masking sound audio files and one or more selectable video files;
- and
- one or more application programs executable by the one or more processors configured to output a noise masking sound audio file selected from the one or more selectable noise masking sound audio files at the plurality of balanced mode radiator loudspeakers and output a video file selected from the one or more selectable video files at the display device.

A method for masking open space noise comprising:
- outputting a noise masking sound from a plurality of balanced mode radiator loudspeakers distributed in a down-fire direction above an open space, the plurality of balanced mode radiator loudspeakers disposed at a desired height above an open space floor and wherein a total number of balanced mode radiator loudspeakers within the open space is selected based on the desired height above the open space floor;
- and
- displaying a visual corresponding to the noise masking sound.
A system for masking open space noise comprising:
- a plurality of balanced mode radiator loudspeakers arranged above an open space to output a noise masking sound in a down-fire direction, each balanced mode radiator loudspeaker of the plurality of balanced mode radiator loudspeakers comprising a voice coil, a diaphragm, and one or more mass objects coupled to the diaphragm;
- a plurality of microphones;
- and
- one or more computing devices comprising:
- one or more processors;
- one or more memories storing one or more application programs executable by the one or more processors, the one or more application programs comprising instructions to receive a microphone data from at least one of the plurality of microphones and adjust the noise masking sound output at one or more of the plurality of balanced mode radiator loudspeakers.
