摘　　要：汽车驾驶室因噪声直接危害驾驶人员的身体健康 ,引起生理和心理上多种疾病 ,还会诱发交通事故 ,影响工作效率。我国运材汽车均为载重汽车 ,由于车辆本身和使用条件等方面的原因 ,驾驶室内噪声较大。本文针对我国运材生产中经常使用的两种车型驾驶室内噪声的调查为基础 ,进行有关的试验测试 ,并利用频谱和相干函数理论 ,建立了在多输入单输出情况下驾驶室内主要噪声源及试验系统模型。经过试验 ,对运材汽车驾驶室内噪声进行了评价 ,验证了所建立的系统模型的正确性 ,确定了驾驶室内噪声及其主要来源。Noise in cabin of truck endangers the driver's health directly and leads to many physiological diseases. It can also bring about traffic accidents and influence work efficiency. In our country, log hauling trucks are all heavy trucks. Because of trucks themselves and using conditions, noise in cabin is very loud. Some tests were made based on the investigation of noise in cabins of two kinds of trucks that were often used in China. The model of testing main noise source in cabins was founded under many inputs and one output by spectrum and coherent funcetion theory. After tests noise in cabins was evaluated and the correction of the model was verified. The noise in cabins and its resource were also defined.
