Sound (1x2)

Air date: Sep 02, 2014

In this episode we journey through the world of sound – from the deepest rumbles to the highest squeaks. Using specialized technology Helen and Patrick reveal how alligators use low pitch rumbles to make the water around them ‘dance’, show what it’s like to be a bat and to ‘see’ with sound, and convert a classic camper van into a giant speaker to conduct the ultimate hearing test for a herd of elephants.
