The device uses a dog’s bark to trigger an ultrasonic circuit, which emits a piercing sound (ineffective to humans but effective to dogs). This sound is sufficiently unpleasant to cause the dog discomfort and stop its barking (without causing any harm to the dog). After repeated exposure, the dog learns that this sharp sound is triggered by its own barking and consequently ceases to bark.
