摘　　要：在电力企业厂界噪声监测工作中,存在背景噪声难以测量和修正的问题。提出了点声源随距离衰减模型,并基于"非同时性"、监测指标、运行工况等对测量方法进行了改进。针对被测噪声和背景噪声的差值小于3和不为整数的噪声值、稳态或非稳态的情况进行了修正,对实际工作具有一定的指导作用。In the actual boundary noise monitoring of electric power enterprises, the problems exists that the background noise is difficult to be measured and corrected. A sound source level with distance attenuation model is proposed, and the measure- ment method is improved based on the ＂non -simultaneity＂ , monitoring indicators, operating condition and so on. Some cor- rections are carried out for the measured noise and background noise which is less than 3 and for the noise value which is not an integer as well as the steady and unsteady noise, which has a guide meaning for the actual work.
