Apparatus, system, and method of active acoustic control (aac)

An apparatus comprising:

• an input to receive input information, the input information comprising:
• noise information representing acoustic noise at a plurality of noise sensing locations;
• residual-noise information representing acoustic residual-noise at a plurality of residual-noise sensing locations within a sound control zone;
• and
• Active Acoustic Control (AAC) configuration information representing one or more parameters affecting a real-time configuration of AAC in the sound control zone;
• a controller configured to determine a sound control pattern to control sound within the sound control zone, the controller configured to determine the sound control pattern based on the AAC configuration information, the noise information, and the residual-noise information;
• and
• an output to output the sound control pattern to a plurality of acoustic transducers.

A product comprising one or more tangible computer-readable non-transitory storage media comprising instructions operable to, when executed by at least one processor, enable the at least one processor to cause a controller of a sound control system to:

• process input information, the input information comprising:
• noise information representing acoustic noise at a plurality of noise sensing locations;
• residual-noise information representing acoustic residual-noise at a plurality of residual-noise sensing locations within a sound control zone;
• and
• Active Acoustic Control (AAC) configuration information representing one or more parameters affecting a real-time configuration of AAC in the sound control zone;
• determine a sound control pattern to control sound within the sound control zone based on the AAC configuration information, the noise information, and the residual-noise information;
• and
• output the sound control pattern to a plurality of acoustic transducers.
