Helen investigates how Big Ben creates pressure waves at particular frequencies, how soprano Lesley Garrett's singing voice works, the deep tones of a volcanic eruption and the sounds made by a black hole in space.
Helen visits a hidden location in Scotland to experience some extreme acoustics. She discovers how sound diffracts and so helps us to sense danger and how our ears translate vibrations into electrical signals.
