In a great many instances it has been shown that modern methods of sound-proofing make it possible to place a ballroom or bowling alley room either directly above or directly under a theatre auditorium, with positive assurance that noise will not reach the auditorium and interfere with the audience enjoying the program. Proper sound-proofing in such instances is an individual problem, due to the difference in building constructions, methods of ventilating, etc. The accomplishment is a matter of using proper design and materials based on years of successful installations. The system is based on proper breaking of solid contacts combined with proper absorbing mediums. With this system it is possible to place refrigerating apparatus, pumps, ventilating fans and motors, converter sets, etc., in any part of a building without fear of disturbance. In case a theatre auditorium is to be located in a large office building, the system can be used to prevent sound of pipe organs from penetrating to office spaces. C. F.
