Flanking transmission can seriously degrade the performance of building elements in the field. In cases of very poor construction, the actual field transmission loss may bear very little resemblance to the laboratory data. A facility has been constructed to examine the effects of flanking transmission in wood-framed construction. Measured sound insulation data are presented for partitions with potentially common construction faults. The faults considered are rank ordered as to their severity. Standard airborne and impact tests, surface velocity and intensity measurements are also assessed for their effectiveness as measurement tools.
