Piezoelectric detection coupling of a bark collar

A method comprising,

• receiving a filtered signal from a filtering component of a collar device, the filtering component for receiving and filtering an electrical signal from a piezoelectric element, wherein the piezoelectric element is configured to receive vibrations of at least one acoustic event from a metal electrode probe, wherein the metal electrode probe is secured to a receiving cavity of the collar device, wherein at least one elastomeric ring encircles the metal electrode probe, wherein the at least one elastomeric ring mechanically isolates the metal electrode probe from the receiving cavity, the receiving the vibrations including generating the electrical signal proportional to the frequency and magnitude of the vibrations;
• applying a plurality of tests to the filtered signal in a sequence, wherein each test of the plurality of tests assesses the filtered signal for a presence of one or more characteristics, the determining the presence of the one or more characteristics comprising a determination that the at least one acoustic event is not a bark of an animal;
• terminating the applying the plurality of tests when a test determines that the at least one acoustic event is not a bark of the animal;
• and
• identifying the at least one acoustic event as a bark of the animal upon an occurrence of completing all tests of the plurality of tests, the completing all tests including each test in the sequence failing to determine that the at least one acoustic event is not a bark of the animal.
