System and method are disclosed to mitigate noise in an area monitored by a plurality of telecommunication terminals in communication with a controller, the method including: detecting an excessive noise originating in the area monitored by the plurality of telecommunication terminals, the detection performed by one or more terminals of the plurality of telecommunication terminals; identifying a location of a first terminal of the plurality of telecommunication terminals by use of the detected excessive noise, wherein the first terminal is closest to a source of the excessive noise; and providing a mitigation message to the identified first terminal.
1. A method to mitigate noise in an area monitored by a plurality of telecommunication terminals in communication with a controller, comprising:
detecting an excessive noise originating in the area monitored by the plurality of telecommunication terminals, the detection performed by one or more terminals of the plurality of telecommunication terminals;
identifying a location of a first terminal of the plurality of telecommunication terminals by use of the detected excessive noise, wherein the first terminal is closest to a source of the excessive noise;
providing a mitigation message to the identified first terminal;
counteracting excessive noise generated at the first telecom terminal, by selecting a first counteractive measure selected from a predetermined group of counteractive measures, wherein members of the group of counteractive measures differ in a level of intrusiveness;
waiting a predetermined period of time and
if excessive noise is still detected at the first telecom terminal, counteracting the excessive noise generated at the first telecom terminal by use of a more intrusive counteractive measure selected from the predetermined group of counteractive measures.
2. The method of claim 1 , wherein the first terminal is in acoustic proximity to a second terminal of the one or more other terminals of the plurality of telecommunication terminals.
3. The method of claim 2 , wherein acoustic proximity comprises less than a predetermined level of acoustic attenuation of an acoustic signal emitted at the first terminal and received at the second terminal.
4. The method of claim 2 , wherein acoustic proximity comprises receiving, by the second terminal, an acoustic signal emitted at the first terminal, such that an intensity of the received signal is at least a predetermined level above an ambient noise intensity at the second terminal.
5. The method of claim 1 , wherein the step of identifying the location of the first terminal comprises correlating audio signals detected at one or more terminals of the plurality of telecommunication terminals.
6. The method of claim 5 , wherein the step of correlating audio signals comprises adjusting for uncertainty in terminal location.
7. The method of claim 1 , further comprising: tracking, by the plurality of telecommunication terminals, sound intensity level variations measured by at least one of the plurality of telecommunication terminals.
8. The method of claim 1 , further comprising: providing an excessive noise warning to the first telecom terminal.
9. The method of claim 1 , further comprising: providing an excessive noise warning to telecom terminals that are in acoustic proximity to the first telecom terminal.
10. The method of claim 2 , wherein acoustic proximity is determined by: emitting, at the first terminal, an audible signal having known intensity; and measuring audible intensity of the audible signal as received at the second terminal.
11. The method of claim 1 , further comprising: providing a warning of an absence of an expected noise at the first telecom terminal.
12. The method of claim 1 , wherein the step of detecting the excessive noise comprises correlating audio signals detected at one or more terminals of the plurality of telecommunication terminals to stored signatures of known acoustic events.
13. The method of claim 1 , wherein the excessive noise is counteracted only if other users are within acoustic proximity to the first telecom terminal.
14. The method of claim 1 , wherein the predetermined group of counteractive measures comprises disabling at least a portion of the functionality of the first telecom terminal.
15. The method of claim 1 , wherein counteracting the excessive noise generated at the first telecom terminal by use of a more intrusive counteractive measure comprises:
polling users of telecom terminals that are acoustically proximate to the first telecom terminal about an extend of noise annoyance; and
presenting poll results to a user of the first telecom terminal.
16. A system to mitigate noise in an area, the system comprising:
a plurality of telecom terminals, each telecom terminal comprising a microphone;
an audio sensor array formed from the microphones in the plurality of telecom terminals;
a controller in communication with the plurality of telecom terminals, the controller configured:
to receive audio measurements of an excessive noise from the audio sensor array; and
to identify a location of a first terminal of the plurality of telecom terminals by use of the detected excessive noise, wherein the first terminal is closest to a source of the excessive noise;
to counteract excessive noise generated at the first telecom terminal, by selecting a first counteractive measure selected from a predetermined group of counteractive measures, wherein members of the group of counteractive measures differ in a level of intrusiveness;
to wait a predetermined period of time; and
if excessive noise is still detected at the first telecom terminal, to counteract the excessive noise generated at the first telecom terminal by use of a more intrusive counteractive measure selected from the predetermined group of counteractive measures; and
a transmitter configured to transmit a mitigation message to the identified first terminal.
