    "abstract": "The various factors that must be considered in the acoustical design and treatment of theaters are outlined, as a guide to architects and engineers in solving the more common problems arising in this particular phase of motion picture engineering. Fundamental considerations, such as proportions, shape, sound insulation, stage, etc., are briefly covered. The relation of “fixed” absorption to surface acoustic treatment is also discussed. Curves recommended by Electrical Research Products, Inc., showing optimal and percentage optimal reverberation times as functions of volume and frequency, respectively, are offered. Particular stress is placed upon the necessity of carefully selecting the materials for theater treatment with respect to their sound-absorbing efficiencies throughout the frequency range.",
