| 摘 要： | 在系统研究主动噪声控制技术和柴油发电机房内噪声来源的基础上，作者提出了一种利用复合主动噪声控制思想，改善柴油发电机房内噪声环境的方案，具体地说，就是采用反馈主动噪声控制系统，抵消发电机房低频噪声的总辐射，还采用前馈主动噪声控制系统，抵消柴油发动机噪声的基频分量及其多次谐波分量，分析表明，该方案具有较好的除噪效果和较高的实用价值。 |

| Abstract: | This paper presents a scheme of reducing noises inside the diesel generator room by means of the hybrid active noise controlling. In bases on the systematic researches on the technology of active noise controlling and the analysis of noise sources inside the diesel generator room. The proposed scheme can attenuate the total noise radiation from low frequency noises when a feedback controller is used, and can also attenuate the base and harmonic frequencies of the engine noises when a feedforward controller is used. Analyses indicate that the presented scheme can reduce the diesel generator room noises effectively. |
| Keywords: | active noise control feedforward controller feedback controller |
