随着社会的不断进步和经济的高速发展,四大污染之一的噪声污染越来越不能被忽视.作为人们生活水平提高的标志之一的空调所产生的噪声,也越来越受到关注.长期受到噪声刺激,将导致听力损失,甚至引起心血管系统、神经系统及内分泌系统等方面的疾病.噪声污染不仅危害人们的健康,还影响人们的生活和工作.通过对引起空调电机噪声的原因进行分析,阐述了在电磁、机械和空气动力方面对设计和制造过程中能够降低电机噪声的方法,并简单介绍了噪声分析和隔消音的方法以降低噪声污染.%With the progress of society and rapid economic development,noise pollution is becoming more and more serious. People are paying more and more attention to the air-conditioning noise. Long-term noise pollution induces hearing loss,disea-ses of cardiovascular,nervous and endocrine systems. Noise pollution not only endangers the health of human beings,but also af-fects people's daily lives and work. This paper analyzes the reasons of air-conditioning motor noises,presents some methods to reduce the noise through design and manufacturing process on electromagnetism,mechanic and aerodynamic aspects. It also intro-duces some methods for noise analysis and insulation to reduce noise pollution briefly.
