| Abstract: | We analysed noise change trend on the basis of noise monitoring data of four functional areas in Harbin City,and found out that average value of Leq noise in 1,3,4 type functional areas were stable,but the sound sources of type 2 functional area were complex.There were more frequent sudden noise in type 2 functional area. |
