In this tour of the worlds most unexpected sounds, Trevor Cox--the David Attenborough of the acoustic realm (Observer)--discovers the worlds longest echo in a hidden oil cavern in Scotland, unlocks the secret of singing sand dunes in California, and alerts us to the aural gems that exist everywhere in between. Using the worlds most amazing acoustic phenomena to reveal how sound works in everyday life, The Sound Book inspires us to become better listeners in a world dominated by the visual and to open our ears to the glorious cacophony all around us.
