Centralized control of multiple active noise cancellation devices
The invention relates to a method for centralized control of multiple active noise cancellation devices. The method includes identifying a trigger event. Also, the method includes identifying, in response to identifying the trigger event, two or more zones of a mapped area. Further, the method includes identifying, based on the two or more zones, two or more devices. Still yet, the method includes transmitting a command to disable active noise cancellation on each of the two or more devices.
1. A method, comprising:
receiving metadata from a sound masking control system;
identifying a trigger event based on the metadata;
in response to identifying the trigger event, identifying two or more zones of a mapped area;
based on the two or more zones, identifying two or more devices; and
transmitting a command to disable active noise cancellation on each of the two or more devices.
2. The method of claim 1 , wherein the metadata is generated by the sound masking control system based on communications monitored in the mapped area.
3. The method of claim 1 , comprising receiving second metadata from a personal audio device in the mapped area, wherein a second trigger event is identified based on the second metadata.
4. The method of claim 3 , wherein the personal audio device includes one of a headset and a headphone.
5. The method of claim 1 , comprising:
identifying at least one zone of the two or more zones based on a source of the metadata; and
identifying another zone of the two or more zones based on a content of the metadata.
6. A system for centralized control of active noise cancellation, comprising:
an area mapping of an indoor environment;
a keyword library;
a listing of user and device associations;
a listing of device locations;
at least one processor; and
memory coupled to the at least one processor, the memory having stored therein instructions which when executed by the at least one processor, cause the at least one processor to perform a process including:
receiving metadata, from a sound masking control system based on an utterance detected within the indoor environment by the sound masking control system, that identifies a keyword of the keyword library,
based on the metadata, identifying a trigger event,
in response to identifying the trigger event, identifying, using the area mapping, two or more zones of the indoor environment;
based on the two or more zones, identifying, using the listing of user and device associations and the listing of device locations, two or more devices; and
transmitting a command to disable active noise cancellation on each of the two or more devices.
7. The system of claim 6 , wherein the area mapping comprises a data record that describes spatial relationships between the two or more zones of the indoor environment.
8. The system of claim 6 , wherein the listing of device locations comprises a data record that correlates each device of the two or more devices with a zone of the indoor environment.
9. The system of claim 6 , wherein the listing of user and device associations comprises a data record that correlates a person with at least one of a computing device within the indoor environment and a personal audio device within the indoor environment.
10. The system of claim 6 , wherein the instructions of the memory, when executed by the at least one processor, cause the at least one processor to perform the process including: receiving second metadata from a personal audio device based on an utterance detected by the personal audio device.
11. The system of claim 6 , wherein the instructions of the memory, when executed by the at least one processor, cause the at least one processor to perform the process including: receiving second metadata from a computing device based on an electronic message sent between two computing devices within the indoor environment.
