Review and Perspective of the Active Control Technology for Engine Exhaust Noise |
| |
Abstract: | Firstly, time domain and frequency domain characteristics of the engine exhaust noise and its active control method have been discussed briefly. Then, an overall review of the development of the active control technology for engine exhaust noise is presened at length.Finally, the insufficiencies of its past study are pointed, and the perspective of its further study is suggested. |
