Transmission loss for a muffler with a simple expansion chamber is evaluated using Coustyx indirect BE model. Coustyx solution is validated against published experimental measurements by Z. Tao and A. F. Seybert [1] and analytical solutions with plane-wave assumption. 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.
