Evaluation of Noise Environment Quality Based on Comprehensive Pollution Index Method
Based on comprehensive index method,the environmental noise of unban area,road traffic and functional region in the downtown area of Quanzhou City from 2017 to 2022 were eva-luated.The comprehensive pollution indexes of urban area environmental noise were 1.70～1.83,ranked at the second level.The indexes of road traffic noise were 0.82～2.03,stood at the first,second and third level.The indexes of functional area noise were 0.61～10.7,with some diffe-rences in the same functional area from 2017 to 2022.The evaluation grade was the best in the se-cond types of functional area,and not lower than the third level,while the worst in the forth types of functional area.Compared with the single factor evaluation method,the comprehensive pollution index method not only took into account the equivalent sound level,but also considered other fac-tors,such as noise pollution level,the number of people affected by noise,the standard exceeding rate,the length of road that equivalent sound level excel the standard,so it can reflect the practical situation of noise environmental quality,and the evaluation results were more reasonable.
