摘要
噪声预测是机场周围地区进行土地使用规划并确定机场新建或扩建可行性的重要依据 .本文采用计权等效连续感觉噪声级 LWECPN作为机场噪声评价参数 ,具体结合机场及周围地区的地形、航班、机种及飞机起降航迹等计算并绘出机场周围地区的等声级噪声暴露图 .
Noise prediction is an important basis of land use programming and the feasibity of new built and extened built airport inn the vicinity of an airport.This paper adopts weighted equivalent continuous perceive noise level as airport noise rating paramenters,moreover,it combines the topography,scheduled flight,airport types and departure or approach flight paths,etc,and it computes and draws the noise contours.
