How does it work?
1. When outdoor barking is controlled within the barking range of dogs, the microphone receives sound and the device starts automatically.
2. Outdoor bark control emits ultrasound (which can be heard by dogs but is silent to humans).
3. The dog is frightened by the high-pitched voice. It should stop barking. It will associate its barking with this unpleasant sound.
4. When the dog stopped barking, the ultrasound stopped.
