Sound Waves: The Symphony of Physics

Alternative title: Making Sound, Using Sound
Synopsis: BBC documentary series exploring the physics of sound. In the first episode, MAKING SOUND, scientists from the University of Leicester use lasers to reveal how Big Ben vibrates and creates waves at particular frequencies that then produce the bells’ distinct sound; at the summit of Europe’s most active volcano, Stromboli, volcanologist Dr Jeffrey Johnson uses a special microphone to record the deep tone produced by the volcano as it explodes; at the University of Cambridge’s Institute of Astronomy, we meet a scientist who has discovered evidence of sound waves in a giant black hole. The second episode, USING SOUND, explores how sound has driven the evolution of biological systems and complex relationships between creatures that exploit sound for hunting and to escape from predators; the story of a patient with a cochlea implant shows the complicated way our ears can translate sound waves - a physical vibration in the air - into an electrical signal our brain can understand; on the cold North Sea, marine archaeologists use sound waves to uncover the remarkable human stories buried beneath the sea.
