Ultrasounds are sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from 'normal' (audible) sound in its physical properties, only in that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy, young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often in medicine. In this area, it uses these high-frequency sound waves to look at organs and structures inside the body.

Health care professionals use it to view blood vessels, the heart, kidneys, liver, and other organs in the body. Docturs use ultrasounds during pregnancy to view the fetus.
