Dog whistle: this is one of the most useful tools used to bring back a dog. Not only does sound of a tube form dog whistle that humans can hear, but it also produces ultrasonic frequencies that only dogs can hear. This frequency ultrasound is so far away that the dog can hear it in the distance.
Ultrasonic wave: ultrasonic energy is large and propagated along the straight line. The ultrasonic waves emitted by the dog whistle can be clearly identified by the dog. The owner can use the dog whistle to blow out different tones to give instructions. Depending on the rhythm of the sound, you can let the dog understand the meaning of each rhythm and the instructions given.
