When the Guns Fell Silent

This remarkable recording is not an actual sound recording of the end of World War I, but a modern interpretation of actual data collected during the last minutes of the war using a technique called "sound ranging."  Sound ranging was a crude sort of direction-finding technology used to triangulate the location of enemy artillery by producing a visual record of sound intensity on photographic film.  Someone operating one of these sound ranging systems thought to make a record of the cease-fire and preserve it for posterity.  Today this piece of film is in the custody of the British Imperial War Museum.  In 2018, to commemorate the hundredth anniversary of the Armistice, the Museum commissioned a sound production company to make a recording based on the data on the film.
