Dolphins echolocate with two-part acoustic beams – technology that could help us improve medical and navigational technology
Why do dolphins need echolocation? Dr Josefin Starkhammar:
They use it for navigation, hunting for prey and possibly in social contexts. Dolphins always use acoustics as their primary sense. They generate short sound pulses, which bounce off surfaces and come back as echoes – the time it takes to return is a measure of how far away an object is. The beam is quite focused, so the dolphins turn their heads to scan their environment.
