随着铁路客车运行速度的提高,高速动车组司机室的噪声问题愈发凸显出来,如何有效地控制司机室噪声,为司机提供良好的工作环境就显得尤为重要。采用BK相控球阵列噪声源分析仪,对司机室主要噪声源进行分析,为改善司机室内部声学环境、降低车内噪声水平提供依据。 With the increase of the speed of railway passenger cars, the noise problem in the cab of high-speed EMUs becomes more and more prominent. How to effectively control the cab noise and provide a good working environment for drivers is particularly important. The BK phase-control ball array noise source analyzer was used to analyze the main noise sources in the driver’s cab, which provided the basis for improving the acoustic environment inside the driver’s cab and reducing the noise level in the car.
