Acoustic insulation and sound transmission in cold-formed steel construction
Introduction Acoustic insulation criteria often dominate the design of floors and walls in multi-occupancy dwellings such as apartments or hotels. Even in single dwellings it may be necessary to consider some method of sound reduction (attenuation) between particular rooms. Although sound insulation construction will add to building costs, the expenses of correcting acoustical mistakes usually are several-fold higher. The purpose of this publication is to review acoustic criteria for the design of internal floors and walls, to present acoustic performance requirements for different types of buildings, and to provide a list of resources and available test data.
