【摘要】 以国际民航组织(ICAO)推荐的计权等效连续感觉噪声级(LWECPN)为评价参数,利用Visual C++编程,直接调用等值线绘制工具Surfer中的各种数学模型,实现噪声等值线绘制的自动化.并以浙江省某机场为实例绘制了噪声等值线图,该方法大大提高了绘图的效率,预测值与实测值的误差约为1.6~2.6dB.更多还原

【Abstract】 Taking the LWECPN (weighted equivalent continuous perceive noise level) recommended by ICAO (International Civil Aviation Organization) as rating parameter and utilizing various mathematical models in the contour drawing software Surfer transferred directly by the program in Visual C++ Code, noise contours can be drawn automatically. Taking certain airport in Zhejiang Province as example, the noise contours was drawn. This method improves greatly the efficiency of drawing and the error between the value of prediction and the actual value is about 1.6~2.6dB.更多还原
