| 摘 要： | 机场周围飞机噪声的噪声级LWECPN数据来自网格布点监测,这些数据可视为连续曲面上的离散点。寻求利用有限的监测数据,拟合机场周围飞机噪声影响区域内噪声级的曲面分布,根据噪声级精确度允许误差的要求,采用统计检验的方法,确定拟合函数模型的精确度,从而得到机场周围飞机噪声的噪声级等值线分布图。

| Abstract: | The data of noise level(L_(WECPN)),made by airplanes' noise around the airport,came from the netted fix-points testing.These data can be regarded as scattered points on the continual curved surface.The article seeks to make use of the limited tested datum together with camber distribution of noise level in the area affected by planes around the airfield.And based on the requirement of error allowed in the precision of noise level,it defines the accuracy of intended functional model with the method of statistical inspection,and obtains the isograms of noise level from the planes' noise surrounding airport. |
