    Research output: Contribution to journalArticle

    Abstract

    One of the factors affecting the acoustic performance of masonry cavity walls is the type of wall tie used in the construction. The dynamic stiffness parameter allows wall ties of equivalent dynamic stiffness to be identified without involving other variables involved in laboratory airborne sound transmission across masonry cavity wall constructions such as cavity damping and structural coupling at the boundaries. This is useful when one type of wall tie is established in national building regulations and architects or construction companies require the use of non-generic wall ties. © 1998 The Building Research Establishment.
