Sound transmission through a double wall with a masonry leaf and a lightweight leaf is examined by using statistical energy analysis (SEA). Some of the theory necessary to predict transmission is well documented and common to other forms of construction. Additional expressions are provided to accoun

โฆ Synopsis
Acoustic &&breakout'' and &&breakin'' through duct walls had, until the late 1970s, been a rather neglected topic of research, particularly in the "eld of heating, ventilating and air-conditioning ducts. Since then, interest has grown and many publications have appeared in which predictive methods have been reported. Research in this area, especially that which has been conducted over the past two decades, is reviewed in this paper. E!orts are made to identify the main physical processes involved and to present some relevant published data, rather than to give a "nely detailed, comprehensive, account of this research. Some comments are made concerning the possible direction of future research.

A theoretical model of sound transmission across metal ties in a cavity wall is presented in which power flows across independent point contacts between the two leaves of the wall. From a knowledge of the mobilities of the walls and the tie stiffness, the power flow across the ties can be determined
A predictive model for sound propagation in tubes with permeable walls is presented. In this, acoustic coupling between the internal and external sound "elds is taken into account by the use of an iterative procedure that involves "nite-length &&cells'' of uniform properties in the tube and an appro
