机场飞机噪声的预测研究
Study on Noise Prediction of Airport
摘要
Abstract
In this paper, a case study was conducted in Guangban Airport to research the airport noise adopting the Weighted Equivalent Continuous Perceive Noise Level （LWECPN） recommended by International Civil Aviation Organization （ICAO） as a rating parameter. By means of quantitative analysis using MATLAB, a linear equation was set up to describe the aircraft noise level at monitoring points around the airport versus the logarithms of the distances between the monitoring points and the nmway centerline. Then the linear equation was used to predict the LWECPN of the points else and compared with the data determined. The results showed that the predicted values were close to the measured values with relative error ranging in 1.0% ~ 2.0%. It should be emphasized that this method is easy to operation and it is quick to obtain the results. It provides a new prediction method for noise prediction, having practical significance.关键词
