The noise attenuation level of exhaust silencer for Diesel Multiple Unit (DMU) were measured. The direct noise from the engine were also measured. The contribution of these noise sources are simulated. About the exhaust noise were simulated by FEM and CFD. Such simulations are compared to the measurement results.
