Let's Hear About...The Air Raid Siren

Send us Fan Mail The Air Raid Siren There are some sounds that need no explanation. The moment you hear an air raid siren, you know something is wrong. But the story of the siren begins long before the Second World War, and surprisingly, it wasn't invented as a warning at all. In this episode of Let's Hear About… Sounds from History, we travel from an eighteenth-century experiment in sound and music to the sirens that warned millions of people during the Blitz. We discover how a simple scientific instrument could produce the unmistakable rising and falling wail we know today, why the sound changes pitch, and even how the technology was used to measure the speed of a mosquito's wings. We'll also hear about Britain's first wartime air raid warnings, the all-clear signal, the experience of waiting in shelters during the Blitz, and the role the siren later played in Britain's Cold War four-minute warning system. Two sounds made from essentially the same idea, one meaning danger, the other meaning safety. The technology may have changed, but the warning's purpose hasn't.
