Answer 2

Answer:

A special whistle that can produce ultra sound, not heard by humans, is called Galton's whistle. It is used to train dogs because they can hear ultrasounds up to a frequency of 40000 hertz.

These are the special whistles that produce sound of frequency higher than 20,000 Hertz. Dogs have the ability to hear it but humans cannot. Ultrasound scans produce sounds in this range.
