摘要
随着人们对居住环境要求的提高,变电站特征低频噪声对人体产生的影响逐渐引起重视。研究变电站低频噪声带给人的主观感受成为了关键,以实际变电站厂界排放噪声为对象,进行烦恼度分析,并结合现有标准,提出了特定数值建议。研究结果发现,55dB(A)是噪声烦恼度突增点,而响度则决定了烦恼度的大小,与烦恼度呈显著正相关。该结果为变电站预估和控制噪声污染提供了参考。
With the improvement of people's requirements for living environment,the impact of substation characteristic low-frequency noise on human body has gradually attracted great attention.The study of subjective feelings of low-frequency noise in the substation has become the essential part.Therefore,this paper takes the noise emitted at the boundary of the actual substation as the object,analyzes the annoyance degree and puts forward the limit suggestions combined with the existing standards.The results show that 55 dB(A)is the sudden increase point of noise annoyance,and loudness determines the annoyance,which is significantly positively correlated with annoyance.The results provide a reference for the prediction and prevention of noise pollution in substations.
