Seeing with sound

What do bats, dolphins and trawler men all use: and what is the link to baby scans?


Sound and Vibration Research


How bats and dolphins use ultrasound to find their prey by echolocation. The use of sound to image the seabed and wrecks will then be demonstrated. Finally the use of ultrasound to scan the human body will be illustrated, with examples of baby scans and Doppler ultrasound.

Why is this important?

Ultrasound gives us a way of seeing things where light doesn’t penetrate; the systems don’t have to use ionising radiation and are relatively inexpensive!
