| Abstract: | A low noise design of a microbus is described.Through identifying the noise source of the microbus,a noise shield control technology on the engine was used,and seat sealing property of floor was improved,sound pressure level of the engine noise which radiates into the outside environment was reduced,and the acoustics environment in the microbus was also improved,and the results are proved by a test. |
