1. 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.
