History of Sound 11820 to 19251820 Barrel organs bring mechanical music to the streets for the first time. 1878 The first music is put on record: cornetist Jules Levy plays "Yankee Doodle." Inspired by a visit to Edison's laboratories in Menlo Park, New Jersey, a prominent American mechanical engineer named Oberlin Smith conceived the idea of recording the electrical signals produced by the telephone onto a steel wire. He files a patent caveat but not a formal patent.1881 Clement Ader, using carbon microphones and armature headphones, accidentally produces a stereo effect when listeners outside the hall monitor adjacent telephone lines linked to stage mikes at the Paris Opera. 1887 The flat disc is designed by Berliner. Emile Berliner is granted a patent on a flat-disc gramophone, making the production of multiple copies practical. 1888 Edison introduces an electric motor-driven phonograph. 1898 Emile Berliner producing his first shellac discs.
1898 Danish inventor Valdemar Poulsen re-discovers the principle of magnetic recording. Over the course of the next few years he produces practical sound recorders for steel wire and tape. He takes patents in Denmark, the United States, and elsewhere and attempts to sell his patent rights to investors. The machine, called the telegraphone, is described as a device to record telephone messages in the absence the called party. 1900 The telegraphone is described in glowing terms by the technical and scientific press as superior to the phonograph and a great advance in physics as well. 1900 Boston's Symphony Hall opens with the benefit of Wallace Clement Sabine's acoustical advice. 1903 Caruso puts on the motley for the first million seller. 1903 TF The American telegraphone Company formed in Washington, D.C. to manufacture of the telegraphone. American Telegraphone Co. sets up a manufacturing facility in Wheeling, West Virginia to make the machines, and the company initiates a large public stock offering. American telegraphone creates several distributorships across the country to handle service and sales. Telegraphone publicity over the next decade or so promotes the various models of the machine as a dictation system and an automatic telephone recorder. 1906 Lee De Forest invents the triode vacuum tube, the first electronic signal amplifier. 1910 Electronic amplification shows on the scene. 1910 Enrico Caruso is heard in the first live broadcast from the Metropolitan Opera, NYC. 1910 American telegraphone, failing because of bad management and production problems, moves to Springfield, Mass. 1911 Lee De Forest uses his Audion tube, invented in 1907, to make his first practical electronic amplifier. DeForest later tries to apply the amplifier and telegraphone to the making of motion picture soundtracks. 1916 A patent for the superheterodyne circuit is issued to Armstrong; The Society of Motion Picture Engineers (SMPE) is formed. 1916 Edison does live-versus-recorded demonstrations in Carnegie Hall, NYC. 1917 E. C. Wente of Bell Telephone Laboratories publishes a paper in Physical Review describing a uniformly sensitive instrument for the absolute measurement of sound intensity. Then condenser microphone. 1918 American telegraphone enters receivership after having sold only a few hundred machines. The company remains in existence until 1944 when it is finally dissolved. 1923 BBC as a private company is granted its first license. |
