Abstract
A system and method for processing and enhancing utility of a sound mask noise signal, including generating, by a signal processor, the sound mask noise signal by modulating a noise signal with embedded additional information, outputting, by a plurality of audio speakers, sound signals comprising the sound mask noise signal with the embedded additional information; and receiving, by one or more microphones, the outputted sound signals comprising the sound mask noise signal, wherein an impulse response between each audio speaker and each microphone is measured in real time based on the embedded additional information.
Claims21
A system for processing and enhancing utility of a sound mask noise signal, comprising:
- a processor configured to generate the sound mask noise signal by modulating a noise signal with embedded additional information;
- a plurality of audio speakers configured to output sound signals comprising the sound mask noise signal with the embedded additional information;
- and
- one or more microphones each configured to receive the sound signals comprising the sound mask noise signal output from the plurality of audio speakers,
- wherein the processor derives an impulse response between each audio speaker and each microphone in real time based on the embedded additional information while maintaining properties of a sound mask.
