  • Patent number: 10276143
    Abstract: Methods and apparatuses for addressing open space noise are disclosed. In one example, a method for masking open space noise includes receiving a sensor data from a sensor arranged to monitor an open space over a time period. The method includes generating a predicted future noise parameter in the open space at a predicted future time from the sensor data. The method further includes adjusting a sound masking noise output from a loudspeaker prior to the predicted future time responsive to the predicted future noise parameter.

  • Patent number: 10142762
    Abstract: Methods and apparatuses for addressing open space noise are disclosed. In one example, a method for masking open space noise includes receiving a microphone output signal from a microphone, the microphone one of a plurality of microphones in an open space. The method includes detecting a presence of a noise source from the microphone output signal, and determining whether the noise source is capable of being masked with a noise masking sound. The method further includes increasing a volume of a noise masking sound output from a loudspeaker responsive to a determination that the noise source is capable of being masked, the loudspeaker located in a same geographic sub-unit of the open space as the microphone. The loudspeaker is one of a plurality of loudspeakers in the open space.
