AbstractAlthough it is often standard procedure to use resilient channels to improve the sound transmission loss of a wall or floor system, there was no simple model of their performance, nor a quantitative understanding of the important properties of the resilient channels. This paper provides a simple model for explaining the effects of adding resilient channels to a rigid double- leaf wall or floor system. While the model is useful to optimize the low frequency performance of double leaf constructions with resilient channels, it also demonstrates that the practical range of improvement stemming from the use of resilient channels is limited.
