    "abstract": "The general subject of the making and showing of motion pictures in synchronism with sound has been covered recently by papers presented before this society at the last two successive meetings and also in recent articles appearing in many of the current trade and scientific publications. The conception of the idea of sound motion pictures is not new, but practical commercialization of the art has been dependent upon the perfection of sound transmission apparatus and the solution of problems relating to various vital parts of the whole system.",
