针对国内某风电机组冷却系统噪声扰民问题，进行噪声控制。通过振动噪声测试分析确定主要声源，研究设计相应的减隔振方案、消声器声屏障降噪方案以及塔桶内部吸声降噪等方案和相应的减振降噪器件，并开展整体噪声控制方案的实施和评价。最终关键点噪声降低达到22 dB，有效解决了噪声扰民问题，并有效提升该机型海外市场的竞争力。

The noise control of a typical windmill turbine cooling system was studied, including the measurement of noise sources, design of noise control strategy, effects of sound barrier and silencer, materials and devices for sound absorption and reduction etc. The global noise control strategy was implemented and evaluated. As a consequence, the sound level in the key position of the system was reduced to 22 dB, and the noise problem was solved, which can effectively improve the windmill competitiveness in the overseas markets.
