When a dog barks and is in the area covered by the barking control system, the internal microphone catches the sound and the unit is automatically activated to control the dog's barking, by means of this ultrasonic barking control device.
The barking control system for outdoor or indoor use emits ultrasound. Dogs can hear them, but humans can't. Surprised by this high-pitched sound, the dog should stop barking, as it will associate the barking with this unpleasant noise. When the dog stops barking, the ultrasound will also stop.
