Abstract：Visualization of airport noise plays an important role in evaluating the airport noise impact in the vicinity of airports .The airport noise dynamic isoline map can facilitate analysis of the regional influence of airport noise each time of the day for the airport managers and provide scientific decision basis for formulating effective noise reduction measures .After analyzing airport noise characteristics and distribution a kind of efficient algorithm adapting to airport noise dynamic isoline map is presented in this paper .Firstly ,the historical monitoring data of airport is clustered to find the distribution model of the airport noise .By constructing an effective grid and creating route grid ,a rapid dynamic drawing method for isoline map of airport noise is proposed in this paper .The drawing frequency is set as 20 frames per second .The experimental results show that the proposed algorithm has efficient performance ,and meets the the time complexity requirements of airport noise dy-namic isoline map .The gap between the lower sampling rate of airport noise data monitoring and the higher refresh rate of the data can be narrowed ,and dynamic isoline map can be generated rapidly .
