The sound and the picture therefore, being on the same base, it is impossible to seriously interfere with perfect synchronism of sound and motion. The third system records the sound upon what amounts to a phonograph disc record. With this latter system it is always possible that synchronism may be seriously interfered with. Regardless of what system is used, the recording of sound in synchronism with motion pictures in itself presents difficulties of large dimensions, aside from the mere task of recording. That this is true we readily see when it is considered that in the recording of productions, of musical numbers, of monologues and many or even most other things, it is essential to pleasing results that all sounds except those the audiences are supposed to hear be excluded from the record. This means that since extraneous sounds would work harm to, for example, productions in which dialogue is used, the studio in which such productions are made must be as nearly soundproof as possible. If located in a city, then all noises from, and vibrations caused by, pass
