Sound Equipments


Vitaphone is produced by Warner Brother and its sister studio First National from 1926 to 1930. It is the last, but most successful, of the sound-on-disc process. Soundtracks are issued separately on 16-inch phonograph records instead of printed on the actual film. Thus the discs would be played while the film was being projected.

In 1895, Thomas Edison created the Kinetophone, which introduced the basic approach that would become the standard for all cinematic projection before the advent of a video.

Viewers watched the films through a binocular similar to goggle atop the Kinetoscope box, while inserting a tube in each ear. The tubes will then merge into a single tube that in turn was inserted in the phonograph’s receptacle normally used for the amplifying horn. It is even said that these might be the very first ear-buds invented.

In 1913, a different version of the Kinetophone was introduced to the public thanks the the invention of motion picture projection in the 1895. This time, the sound was made to synchronize with a motion picture projected onto a screen. A celluloid cylinder record measuring 5 1/2″ in diameter was used for the phonograph. Synchronization was achieved by connecting the projector at one end of the theater and the phonograph at the other end with a long pulley. However, Edison abandoned sound motion pictures in 1915 due to the difficulty of operating the Kinetophone to achieve synchronizations and several other reasons.
