Abstract
This paper presents an investigation of the growth of the ground noise during the successive stages of the processes involved, from the time of manufacturing the base support until the sound is reproduced in the theater. A study is made of the relation between emulsion grain size and the level of ground noise. When the processing and handling were done with the utmost care, the ground noise was found to decrease continuously as the emulsion grain size decreased. Finally, a study was made of the character of the noise from the standpoint of the relation between its r.m.s. value and its average and peak values, as well as a determination of the noise as a function of frequency.
