针对国内某箱式大功率电机的噪声问题，开展了整体系统的噪声控制。通过噪声测试分析确定声源的性质和传递路径；在现有电机结构的基础上，研究设计了减振降噪方案和开发相应的声学材料，由此实施和评价噪声控制的方案。相比原有消声处理后的电机最终总体噪声从89 dB降低到81 dB，优于现有要求的85 dB的指标。

Noise control of a domestic typical high-power electric motor is studied. Based on the measurement and analysis of the noise of the motor, the contribution and transfer path of the noise sources are determined. The noise reduction scheme is designed and the corresponding acoustic material is developed and applied to the electric motor. The results show that in comparison with the original motor, the overall sound level of the noise can be decreased by 8 dB, which effectively improves the compatibility of this type of motors.
