| Popis: | At 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. Acoustics Week in Canada 2011: 12-14 October 2011, Quebec City, QC |
