Abstract:The sound power sensitivity analysis reveals the relationship between the radiation power caused by the structure vibration with the design variables of the structure. A new method for solution of sound power sensitivity is presented by using acoustic radiation modal model to deal with radiation part and using finite element vibration model to deal with vibration of the structure part. In the plate model with the infinite baffled panel, this method is verified by a common method of using Rayleigh integral model to deal with radiation part. In conclusion, it is proved that this method is feasibility.
