Transmission Loss for a Perforated Muffler

Transmission loss for a perforated muffler with a flow plug is evaluated using Coustyx indirect BE model. Coustyx solution is validated against published experimental measurements by T.W. Wu [1]. Transmission loss is evaluated using the following two methods: Four-pole method and Three-point method. In the Four-pole method two BEM runs are required to compute all four pole parameters, whereas only one BEM run is sufficient to compute transmission loss using the Three-point method.

Download the latest version of Coustyx. Compute transmission loss using the Four-pole method by running demo model DemoModel-4PoleMethod, or using the Three-point method by running demo model DemoModel-3PointMethod. Demo models contain embedded trial licenses valid only for those models. Install Coustyx first to run a Demo Model.
