Abstract
A system and method for sonically connecting special devices is provided. A plurality of devices is monitored. One or more sound profiles are maintained on each of the devices, wherein at least one of the sound profiles on each device is for a sound emitted by one other device in the plurality. A sound is detected on one of the devices and the detected sound is compared to one or more of the sound profiles stored on that device. A match is identified between the detected sound and one of the sound profiles. One or more response actions are performed based on the identified match.
Claims8
A method for sonically connecting communication devices, comprising:
- generating for a training sound, a training profile comprising a frequency only profile and a STFT profile, wherein the frequency only profile comprises a set of energy well coefficients, trigger regions and cutoff thresholds, and the STFT profile comprises different trigger regions and different cutoff functions for a plurality of windows for the sound;
- storing the training sound profile in a memory of a device;
- comparing an observed sound received on the device as an alert to the frequency only profile via a processor of the device;
- assigning via the processor a vote when at least one point along an average power spectrum for the observed sound is greater than or equal to a threshold defined by one such energy well coefficient;
- determining a total number of votes via the processor;
- when the total number of votes is greater than or equal to a predetermined minimum number of votes, comparing via the processor an observation power spectrum for a plurality of windows of the observed sound to the STFT profile;
- comparing each profile window to each observed sound window via the processor;
- and
- determining via the processor that the observed sound matches the sound profile when a predetermined number of matches between the profile windows and the sound observation windows exists.
