摘　　要：针对舰用设备空气噪声倍频带声压级的要求,在分析交、直流电机噪声发声机理的基础上,通过对不同声源频率特性的研究,解决了在设计阶段计算交流异步电机、直流电机空气噪声声功率级和倍频带声压级的问题;并在实际工程设计中得以应用,使所设计的电机符合美国海军标准。In allusion to the requirements of ship equipment＇ s air noise frequency pressure level, based on the phonate elements of AC-DC motor＇s noise, and the research of different sound source frequency characteristics, the problem of AC asynchronous motor, DC motor noise sound power level and frequency band sound pressure level are solved. The system applied in practice, the motor can be in line with the standards of the U.S. Navy.
