摘　　要：介绍目前非公路矿用自卸车国内外噪声法规要求和遵循的标准,给出在动态模式下,非公路矿用自卸车机外发射噪声声功率级、司机耳边噪声声压级的测试方法和数据处理要求,同时提出操作者噪声暴露接触的测试方法,并结合实例介绍相应的降噪措施。The current domestic and international noise regulations and standards for non-road mining dumpers are introduced.The test methods and data processing requirements for sound power level of noise emitted from outside of the non-road mining dumper and for sound pressure level of noise emitted in the driver’s ears under the dynamic mode are given.At the same time,the test methods for the operator’s noise exposure are proposed and the corresponding noise reduction measures are introduced in combination with examples.
