Sound is a form of energy. It happens when something moves rapidly, or vibrates. People and animals communicate by using sound. When voices or instruments play a series of notes, musical sounds are produced.
This book looks at the scientific principles of sound - what it is, how it can be recorded. Find out about echoes and acoustics and learn what happens when a supersonic plane breaks the sound barrier.
