on November 11, 1918, then going silent when the clock strikes 11, the symbolic moment politicians determined the war would end, to try and recreate what that instant may have sounded like.Īccording to the company, the film strip has six lines, one for each microphone in use.

As Richard Connor at Deutsche Welde reports, part of a new exhibit called Making a New World at London’s Imperial War Museum uses those graphic sound waves to recreate the moment the Armistice went into effect and the guns fell silent.Īs part of a celebration to commemorate the 100th anniversary of the end of the war, the museum commissioned the sound production company Coda to Coda to use the film strip of the guns firing away at 10:58 A.M. Using that data and the time between when a shot was fired and when it hit, they could then triangulate where enemy artillery was located-and adjust their own guns accordingly.Īt least one bit of that “sound ranging” film survived the War-the film recording the last few minutes of World War I when the guns finally fell silent at the River Moselle on the American Front. The effect is similar to the way a seismometer records an earthquake. To do so, technicians set up strings of microphones-actually barrels of oil dug into the ground-a certain distance apart, then used a piece of photographic film to visually record noise intensity. Special units used a technique called “sound ranging” to try and determine where enemy gunfire was coming from. Still, there were people on the front recording. Taking such machines into the field was not practical. Magnetic tape didn’t exist yet and recording technology was in its infancy, requiring sound to be mechanically produced using a needle and soft wax or metal. But we don’t actually know quite what the World War I sounded like. The soundscape of the Great War must have been devastating: constant artillery bombardment, rifle shots, fighter planes buzzing overhead and the screams of soldiers encountering gas.
