ABSTRACT
The Curle and Proudman models are used in the simulation of the surface acoustic pressure of an automobile. The simulation results of the original style and two optimization proposals of the side mirror are compared through the two models, which demonstrate that the optimizations can contribute to approximately 3 dB (one scale label) reduction of the surface acoustic power.
