Liên tục các yếu tố cấu trúc và các kết nối tại các mối nối của tường ngăn và sàn nhà cung cấp đường dẫn truyền rằng bằng cách vượt qua các phân vùng tách biệt giữa hai không gian nhạy cảm với tiếng ồn. | M National Research Conseil national Council Canada de recherches Canada MC CMC Guide for Sound Insulation in Wood Frame Construction Research Report 219 March 2006 J.D. Quirt T.R.T. Nightingale F. King Page 1 of 103 Preamble and Acknowledgement This Guide addresses flanking transmission of sound through wood framed construction. Continuous structural elements and connections at the junctions of partition walls and floors provide transmission paths that by-pass the separating partition between two noise-sensitive spaces. Flanking transmission is sound transmission between two rooms by paths other than directly through the nominally separating wall or floor assembly. Flanking exists in all buildings and its importance in determining the apparent sound insulation that perceived by the occupants depends on of the construction details of the walls the floors and their junctions. This Guide is the derivative of four industry-sponsored research projects conducted at IRC NRC. The focus and construction details were decided by a Steering Committee of technical representatives from each of the supporting partners. Partners included Canada Mortgage and Housing Corporation Forintek Canada Corporation Marriott International National Research Council Canada Owens Corning Trus Joist and USG. This Guide supersedes the version published in 2005. This version includes estimates of the flanking due to directly attached gypsum board on ceilings corridor walls and exterior walls. The first version assumed that these surfaces were mounted on resilient channels and thus had negligible effect. Overview of Content and Intended Application The intent of this guide is to present the findings from a substantial experimental research study in a form that can be used as a framework for design. The guide focuses on wood-framed assemblies because that was the priority of the study on which it is based. Other types of walls and floors with concrete or steel .
