film developing history: sound

Sound introduces into film for the first time in the 1927. It provides a representative case for technology to develop Hollywood film history. It can be defined that sound is a very important discovery for film aesthetics and influence deeply in film culture.

In the film history, if silent film is in existence, silent cinema is never existed. The main reason is that cinema always have sound. For example, diorama and lantern slide as the forerunners in film amusement in 18 and 19 century, both of them are multimedia. But it is obvious that sound is just used to reinforce and supply scenes. The silent film is just one part of all performs in the cinema. Video is transcribed previously, and the sound of accompaniment is performed in the interval. Sometimes, the playactors from humanophone company elocnte the dialogue following the scenes. So this form of synchronism is the primal dub, following the technology developing, this form of synchronism is changed, mechanization equipment which can make the sound on a film synchronize with the action instead of people. In fact, before the music synthesizer used extensive, sound technology has already invented. So finance is the first factor which is considered in 1927, technology is not main complication.
