AbstractThe technique of acoustic intensity is used to investigate the sound isolation of lightweight wood frame constructions having various degrees of flanking transmission. The ability of the intensity technique, using a P-P probe, to correctly resolve the radiated sound power of a building element is examined subject to various levels of extraneous noise from adjacent flanking surfaces. The effect on the estimate of sound power is shown to be related to the relative importance of the extraneous noise enclosed in the measurement volume. Masking adjacent surfaces is necessary to achieve a reasonable estimate.
