AbstractAt NRC-IRC, a double leaf wall assembly has been tested with and without a constrained layer damper (CLD) to determine the improvement on the sound transmission loss (TL). In parallel, a Statistical Energy Analysis (SEA) model was derived to estimate the effect of the loss factor on the airborne TL. The theoretical and measured improvements will be compared in this paper.
