A FUNDAMENTAL STUDY ON EXTERNAL ENGINE NOISE PROPAGATION FROM LIGHT VEHICLES

In this paper, we have analyzed the problem of the engine noise propagation and have classified that there is a fundamental relationship between exterior noise and structural design. In the case of light vehicles, we have isolated the following 2 factors in structural design which have a direct bearing on exterior noise: (1) The layout and the area of exposed openings in the engine room; and (2) The ability of the engine room to absorb noise. In conclusion we suggest comprehensive approach to the problem of automotive noise reduction. /SAE/
