When it’s completely silent, can you hear the tiny footsteps of a centipede? Can you hear a snail eat? In series 6 of Bang Goes The Theory, the BBC's Jem Stansfield sets up in a sound proof room to record a few amazingly quiet creatures.
Fun fact: a snail is a mollusk, and there are over 100,000 identified kinds including snails, slugs, clams, oysters, squids, and octopuses. If you study mollusks, you’re a malacologist. If you study sound (and vibrations and other related subjects), you’re an acoustician.
There are more videos with great sounds in the archives.
