Ultrasound

With ultrasound we can make images of things with the aid of sound. By sending out sound and seeing how it bounces back we can look inside a human body or down under the surface of the ocean. Bats navigate by using this technique. The earliest ultrasound technology was the echo sounder. It was developed after the ship Titanic sank in 1912. Ultrasound is cheaper and simpler than X-rays. It has been used in medicine since the 1950s. 

Ultrasound is acoustic oscillations which cannot be perceived by the human ear. With an ultrasound device you can send out and receive ultrasound. The sound bounces back and the device can measure the distance — or even make a picture of what the sound strikes.
