Humans can hear sound around ca. 20 - 20,000 vibrations per second; ultrasound is sound beyond that (faster).
Sound is produced by making the air vibrate - with a vibrating object.
Such sound can be produced by a transducer - specifically, one that uses a physical effect to convert electrical signals into vibrations. Producing a high-frequency electrical signal is relatively easy.

ultrasonic sound waves
What do bats produce that makes it possible for them to sense obstacles?
Ultrasonic sound waves
Why can't we produce ultrasonic waves by loud speakers?
Loud speakers can produce ultrasonic waves. But since the normal purpose of loud speakers is to produce sounds for people to hear, there is seldom a reason to produce sounds that people can't hear (other than to annoy certain animals).
Is bats produce supersonic sound waves?
the bats do not produce supersonic sounds.they produce ultrasonic sounds.Thats the reason we cant hear them
Which animal can hear ultrasonic waves?
whale can hear ultrasonic sound waves.
How can you trace ultrasonic waves?
What?! Trace ultrasonic waves? Are you one hundred per cent cuckoo?! Why would anyone trace ultrasonic waves these days??
