It use different sonic sounds of high frequency. Dogs can hear sound at higher frequencies than humans can. A Dog Whistle exploits this by emitting a high frequency sound to call to a dog. Many dog whistles emit sound in the upper audible range of humans, but some, such as the silent whistle, emit ultrasound at a frequency in the range 18–22 kHz.
