In this video Dr Helen Czerski examines the world of sound waves for the BBC's Earth Science series - using tangible objects to reflect the air pressure changes created by their existence. From using glass and candles, to the effects of hearing loss and how it occurs - it's a great insight into the world of sound visualised. More details here: 

Soundwaves: The Symphony of Physics 
Sound is one of the most vivid ways we interact with the underlying science of the universe. A sound can make us laugh, cry or cower in fear, but it can also help us understand our world, how it works and what it's made of. Sound is something we all take for granted, but, in fact, when you hear something you're listening to the sound of pure physics. In this engrossing two-part series Helen Czerski goes on a spectacular journey into the world of sound to discover what it is and what it reveals about the fundamental forces of nature.
