本文尝试提出了一种简便的预测机场噪声影响的声级——面积数值模型.该模型可用于直接计算因机场运行量变更导致的各声区间影响面积的变化.数值检验结果表明,模型运算结果与实际噪声图模拟值具有很好的相关性,平均相关系数r=0.99936.将本模型应用于厦门国际机场几个未来年份的噪声影响预测研究课题,结果表明,该方法是有效的、可行的.
This paper attempts to propose a simple sound level-area numerical model to predict the impact of airport noise, which can be used to directly calculate the change of influence area caused by the change of airport operation volume. Numerical results show that the results of model operation It has a good correlation with the simulated value of the actual noise figure with the average correlation coefficient r = 0.99936. This model is applied to the prediction of noise impact in several future years at Xiamen International Airport. The results show that this method is effective and feasible .
