Based on the noise level measured at different distances of high voltage overhead power transmission lines of 110 kV, 220 kV and 500 kV respectively,the regulation of the noise attenuation is analyzed, which provides references for noise treatment and the division of noise protection area. The result shows that the audible noises measured at the transmission lines of different voltage level all meet the criterion limit;the generation of noises is not affected by the structural arrangement of transmission lines;and the ambient noises have great effects on the noise of transmission lines.
