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

    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
但实际多难啊
