Abstract
This paper compares estimates of the in-situ sound transmission loss (TL) of an individual building element measured using the acoustic intensity technique to the traditional two-room method (ASTM E336). The comparisons are used to assess the accuracy of TL measurements using the intensity technique in the presence of flanking transmission and reverberant energy. The paper also comments on the benefit of quality control indicators to help assess the suitability of measurement conditions in the receive room. This work supports the creation of ASTM and ISO standards to facilitate the measurement of airborne sound insulation using the acoustic intensity technique.
