A Suggestion of Method to reduce the Radiation Efficiency of Dash Panel of a Passenger Car

The study was performed as reduction method using finite and boundary element analysis on structure-borne noise radiated by dash panel of a real car. The radiation efficiency is used to estimate sound noise of dash panel. Curvature and edges of dash panel have effect on radiation efficiency. The simulation results of dash panel was ensured by comparison between experimental results and simulation results of a simple rectangular plate. (omitted)
