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.
Claims24
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;
- 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 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.

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;
- and
- displaying a visual corresponding to the noise masking sound from the plurality of balanced mode radiator loudspeakers distributed in the down-fire direction above the open space.
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 utilize a microphone data originating 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.
