Placing the sonic egg above 5 ft. from the ground, in the direction from where the dog barking is coming, stops the unwanted sound. The device releases ultrasonic sound, which is audible only to dogs. The range of the produced sound is around 50 ft. Dogs have a hearing capacity, which is four times more than humans. Ultrasonic sound means it has a frequency of 20,000Hz or above, which is not audible to the human ear. Since their hearing is sensitive, they can hear this kind of sound, one of the reasons they behave weird sometimes. High pitched ultrasonic sound has the potential to harm their ears.

How it works
The barking of a dog activates the device, and in response, emits an ultrasonic sound to discourage the barking. The microphone detects the unwanted sound, and a signal is sent to the speaker who starts emitting ultrasonic sound. The production of ultrasonic sounds sustains till the dog is barking; once it stops, the device discontinues producing ultrasonic sound. Mount it on a table or wall for indoor use. For outdoor use, hang it on a tree or mount it on a fence or branch using the mounting hole on the device.
