Sound Transmission Loss Through a Concrete Wall

Application ID: 73371

This model presents a practical and efficient method to compute the sound transmission loss (STL) through a building component, specifically this example treats the case of a concrete wall. The method used here is valid as long as the component has little influence on the acoustic field on the source side. The method is based on assuming an ideal diffuse field on the source side and an ideal anechoic termination on the receiver side of the concrete wall. From the approach used in this model, you can extract an ideal, experiment-independent STL. The obtained results are compared to published experimental data and show good agreement.

This model example illustrates applications of this type that would nominally be built using the following products:
