ul·tra·sound

(ŭl′trə-sound′)
1. Sound whose wave frequency is too high (over 20,000 hertz) to be heard by humans.
2. The medical use of ultrasound waves, especially to produce images of the inside of the body or to observe a developing fetus.

ultrasonic (ŭl′trə-sŏn′ĭk) adjective
Did You Know? Many people own and use simple ultrasound generators: dog whistles that produce tones that dogs can hear but are too high to be heard by humans. Any sound whose frequency is higher than the upper end of the normal range of human hearing (higher than 20,000 hertz—that is, 20,000 sound waves per second) is called ultrasound. (Sound at frequencies too low to be audible—about 20 hertz or lower—is called infrasound.) The familiar medical ultrasound images (of a fetus in the womb, for example) are made by directing ultrasonic waves into the body, where they bounce off internal organs and other objects and are reflected back to a detector. Ultrasonic waves have very short wavelengths, and so they can create images of very small objects. Ultrasound can also be used to focus large amounts of energy into very small spaces, making it possible, for example, to break up kidney stones without making any surgical incisions.
