Some of planet's quietest creatures captured on tape
As the Bang Goes The Theory team investigates some of the noise of modern life, they also find time to measure the sounds of some of the quieter creatures on the planet.
In a sound-proofed room, Jem Stansfield listens in on an experiment to try and catch the sounds of a maggot, snail and the footsteps of a centipede.
Bang Goes the Theory is on Monday 19 March at 19:30 GMT on BBC One. Watch again on iPlayer (UK only) using the link.
