The PetSafe® Outdoor Bark Control Works by emitting an ultrasonic sound whenever your dog barks close by. When the Outdoor Bark Control is within range of a barking dog, an internal microphone picks up the sound and the unit is automatically activated. The PetSafe® Outdoor Bark Control emits an ultrasonic sound. The ultrasonic sound can be heard by dogs but is silent to humans.
