When the doorbell rings or guests arrive, it automatically emits ultrasonic waves in response to the dog's barking.
Since it's ultrasonic waves that humans can't hear, it's quiet and doesn't harm the dog. The average human hearing frequency is 20Hz-20KHz, while dogs can hear in a wide range of 15Hz-120KHz.
