【摘要】 通过对6100型大客车的大量试验研究，认为在噪声控制标准中除对A声级测试结果应规定限值外，还应对整个噪声频带规定限值，以便较全面地改善车内噪声环境。根据该车的结构特点，提出了一系列改善噪声及振动性能的措施，经部分改进试验，取得了良好的效果。更多还原

【Abstract】 From a great amount of experimental research of model 6100 bus,it isconsidered that limiting values should be stipulated for the whole frequency band of noise in addition to that for the experimental result of the sound-level A in the noise control standard so as to improve the noise condition all over inside the bus. The authors have put forward a series of tneasures for improving noise and vibration characteristics according to the constructional features of Bus,and obtained good effect from partial tests with improving measures.更多还原
