摘　　要：简要介绍了发动机排气噪声的特点及其有源消声治理方法;就发动机排气有源消声技术的关键环节及其最新研究情况作了详尽的归纳和总结。评述了目前研究中尚存的问题与不足,并预测了其研究发展趋势。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.
