ultrasonic - Computer Definition
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.
