Abstract
Vibrational intensity investigations provide new perspectives in the field of building acoustics. The first measurements on building constructions were directed to the study of flanking transmission. The present paper reports on a procedure for localizing sound bridges, which was tested successfully with a double wall in our testing facility. A remarkable localization accuracy could be achieved with relatively little effort. Therefore this procedure might be expected to prove useful not only in the laboratory, but also in practical applications, both with double walls and floating floors.
