Abstract

The method of acoustic intensity is used to determine the presence and magnitude of flanking transmission in a common double wood stud construction. Two construction specimens are considered. The first, without a construction fault, represents the ideal case in which there should be no flanking. The second specimen has a potentially common construction fault. The plywood floor decking of the upper rooms is continued across the party line. The results of the intensity measurements are presented for the various surfaces. Difficulties encountered when using the intensity technique in the presence of flanking transmission are also discussed
