Cinema sound : characteristics and 3D acoustic measurements

The problem was the little power given by the phonograph which was incapable to reach large audiences. So at first everyone thought the idead of cinema was meant for individual exhibition. At the end of 1877 Edison and his lab assistent Dickson came up with the Kinetoscope and later in 1894 they put this last in combination with the phonograph creating the first Kinetophone (see fig.3) which was roughly able to syncronize the audio.

Come aveva predetto Moore nel 1965 l’evoluzione della tecnologia ha assunto un andamento esponenziale negli ultimi decenni e questo fenomeno ha ovviamente interessato anche il reparto audio, consentendo una più ambia fruizione di materiale economico ma di buona qualità.
