| Abstract: | In this paper, the exterior noise of a large bus is surveyed. With sound intensity method, major sources of the exterior vehicle noise are identified.Acoustic properties in compartments of the engine and its accessories are also investigated. Based on above tests and analyses, some suggestions are proposed for controlling exterior noise of large bus. And a simulation test on engine noise screening is performed. |
