three principal means of improving NVH
1. reducing the source strength, as in making a noise source quieter with a muffler, or improving the balance of a rotating mechanism;2. interrupting the noise or vibration path, with barriers (for noise) or isolators (for vibration); or
3. absorption of the noise or vibration energy, as for example with foam noise absorbers, or tuned vibration dampers. 任一声源的主要环节莫不包括:
声源——路径——受者
马大猷主编〈〈噪声控制学〉〉
所有的噪声控制手段无不落于这三个环节之间,振动也一样 源控制,隔声处理,吸声处理。 源-路径-受者
简单啊
