Abstract: The development and growth of the modern motion picture sound-stage has almost paralleled that of sound pictures. Weather, lighting technic, and sound recording brought about requirements not originally considered. Modern sound-stages have increased not only in quality but in size, and must have structural strength to withstand the elements. Sound treatment makes necessary other treatment for satisfactory occupancy. Lighting is the greatest contributor of heat within the stage, is variable as to amount and duration, and must be controlled correctly. Size and number of sets are variable and create individual problems, and both the number and types of persons on a sound stage play their parts in relation to the air-conditioning. Construction that retards flow of heat through walls necessitates control of the heat. High-salaried personnel, often in costume, demand comfort while working; less time is lost in make-up retouching and less delay brought about by perspiration dampened costumes. An air-conditioning system should have the ability to heat, cool, ventilate, and clean. Stages are generally maintained at 75°F and 50 per cent relative humidity, with temperature settings above and below, at the option of the occupants. Floor distribution of air has the advantage of more economical removal of rising heat but the disadvantage of placing set construction and personnel too near source of cooling. Overhead distribution has the advantage of better temperature distribution but is less economical in the removal of rising heat from lights. Sound treatment of an installation is necessary for continuous operation. If the system does not operate continuously the heat load builds up so that the system can not adequately regain comfortable conditions during non-shooting periods. Treatment is by both isolation and absorption of sound, and can be accurately determined and specified.
