With the development of society, air conditioning equipment is more and more popular. Meanwhile, the problem of disturbance of air conditioning noise is becoming more and more serious. In this paper, the noise situation of the air conditioning equipment in urban residential areas is investigated. Noise sources are acquired by field sampling. The acoustic characteristics and spectral characteristics of the noise are studied. The annoyance of the air conditioning equipment is studied by subjective evaluation in labs. The results show that the loudness of the low frequency noise of the air conditioners is linearly related with the annoyance. The difference of the annoyance at 60 phon (45 dB(A)) is large (2-5), indicating that using A-weighted sound pressure level is not reasonable for the evaluation of air conditioning noise. This conclusion can also explain why the residents still complain the air conditioning noise although the noise level is below the standard. Finally, it is pointed out that the annoyance is related to age and sex of the residents.%随着社会的发展空调设备越来越普及,伴随而来的噪声扰民问题也日益突出.对城市居民区内空调设备噪声进行调查,通过现场采样获得噪声源,研究其声学特性与频谱特性,并通过实验室主观评价方法来研究其烦恼度情况.结果表明,空调低频噪声的响度与烦恼度呈线性关系,在45 dB(A)～50 dB(A)(60 phon～65 phon)范围内烦恼度值分布均较分散,所以在该范围内针对空调低频噪声采用A计权声压级不能很好得反映烦恼度情况,这也解释了在达标情况下居民仍投诉的情况.空调噪声的烦恼度情况与年龄、性别都有关.
