Abstract:
A sound transmission restricting chamber for reducing the transmission of sound between the outside of said chamber and the inside of said chamber, comprising a plurality of interconnected modular components which essentially surrounds an area in order to form said chamber, wherein a plurality of said modular components comprise an inner wall surface, an outer wall surface, an edge frame structure jointing said inner wall surface to said outer wall surface, which edge frame structure extends around the perimeter of said modular component, wherein a cavity is formed between said inner and said outer wall surface, and wherein said edge frame includes a seal for sealing one component to an adjacent second component, wherein air is withdrawn from each of said modular components in order to establish at least a partial vacuum within the cavities of said interconnected modular components, and wherein each edge frame comprises at least one depressurization opening which can be positioned operatively adjacent to a depressurization opening on an adjacent edge frame from an adjacent modular component, in order to interconnect said modular components, whereby air can be simultaneously extracted from at least two of said modular components.
