ultrasonic

of, concerned with, or producing waves with the same nature as sound waves but frequencies above audio frequencies

ultrasonic

[¦əl·trə′sän·ik]
(acoustics)
Pertaining to signals, equipment, or phenomena involving frequencies just above the range of human hearing, hence above about 20,000 hertz. Also known as supersonic (deprecated usage).

ultrasonic

Sound waves that are beyond the audible hearing range; typically above 20 kilohertz (20,000 Hz). Ultrasonic techniques are found in medicine, which use ultrasound waves to echo back an image of a fetus or internal organ, as well as to administer therapy to various parts of the body. Contrast with infrasonic. See ultrasonic welding and saser.
