济南装载机驾驶室内的噪声源主要有气体传播的噪声和固体传播的噪声。但由于，目前我国工程机械用柴油机性能相对落后，所以对发动机提出过高的要求是不现实的，如果在驾驶室的内部及其连接安装部位设计合理的降噪结构实现驾驶室内噪声控制既是必须的也是切实可行的。

Jinan noise source chamber loader main driving noise and the noise of the gas propagation solid propagation. But because, at present China's construction machinery engine performance is relatively backward, so the engine make excessive demands are unrealistic, if well-designed noise structure and its connection installed in the interior parts of the cab cab noise control to achieve both a must is also feasible.

装载机驾驶室的噪声控制隔振 装载机驾驶室相当于一个隔声罩，具有一定的隔声作用。但是，许多国产装载机装上驾驶室后，驾驶员耳旁噪声不仅没有降低，反而比无驾驶室时增大了许多。究其原因，主要是驾驶室固体声超过了驾驶室本身的隔声降噪效果。固体声主要来自驾驶室壁面的声辐射，因此设法减小驾驶室的振动是降低固体声的关键。装载机驾驶室与车架采用弹性支承，可以隔离柴油机的振动，降低固体声的传递，降低柴油机的基频噪声和高次谐波噪声。

Noise isolation loader loader cab control cab is equivalent to a noise enclosures, with some acoustic effect. However, many domestic loader installed after the cab, the driver not only did not reduce ear noise, but no cab than increased a lot. The reason is mainly the cab solid sound than the cab itself, acoustic noise reduction. Solid sound acoustic radiation mainly from the cab wall,so try to reduce the vibration of the cab is the key to reducing the solid sound. Loader cab and frame with elastic support, you can isolate the engine vibration and reduce sound transfer solid,fundamental frequency to reduce diesel engine noise and high harmonic noise.
