It was first used in transmission of opera from the stage of the Paris Opera House in 1881. Inventor Clement Ader used pairs of carbon telephone transmitters across the stage, mixed down to two separate telephone lines going to the homes of subscribers. They had to have two telephones and put the receivers from each one to their ears. Hyper-binaural ear trumpets were used by the Air Force in the First World War to aid in locating enemy planes. In the 1920’s there were experimental binaural radio broadcasts using a pair of frequencies, with listeners tuning in on a pair of crystal sets. At the 1939 World’s Fair, the binaural dummy head “Oscar” was a major attraction, with people lining up to don headphones and experience what was happening in the room in which Oscar was placed.
