product manual:

The appearance of this product is designed like an alarm clock. The outdoor ultrasonic bark suppressor can be hung on a tree, anywhere in the house or in your yard, it can be hung, placed on a table or other places at will. When the luxury outdoor ultrasonic bark arrester alarm clock detects excessive barking, the microphone will sense the bark and activate the component. At this time, the product will emit a safe high-pitched ultrasonic sound that can be heard by dogs but not by humans. The dog will stop barking when stimulated by the sound. Because ultrasound will make the dog feel uncomfortable, the dog will stop barking.
