A Fundamental Study on External Engine Noise Propagation from Light Vehicles 780173
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.
(2)
The ability of the engine room to absorb noise.
In conclusion we suggest comprehensive approach to the problem of automotive noise reduction.
