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.
