Excerpt from American Cinematographer, Vol. 13: A Technical and Educational Publication of Motion Picture Photography; January, 1933
Summarizing these points, it is found that a film stand ard such as shown in Figure 1 offers: (1) asound track with the highest relative output and lowest ground noise to signal ratio possible on 16 mm. Film, (2) the largest possible picture with greatest screen brilliancy, (3) inter changeability with silent films without adjustment of the projector picture aperture, (4) the most economic and efficient use of the light available for picture projection, (5) greatest volume range for any given amplifier gain, (6) most flexible method of production of 16 mm. Prints, (7) provision for compensation of film and printing losses in the sound track, and (8) use of existing equipment in the laboratories. These advantages are obtained by the omission of one row of sprocket holes, and it has been demonstrated by silent projector owners that this is not a detrimental feature.
