| 摘 要： | 为了提高现场测试的效率和数据的准确度,该文提出了一种基于噪声衰减原理而建立虚拟噪声源的方法.利用该方法,可以根据有限的实际测量数据,对实际测点周边的噪声值进行预测计算,绘制噪声传播线图,过程简便,结果一目了然.通过该方法计算的预测噪声值与实际值进行比较,验证了该方法的精度和可行性,比较客观地反映了区域噪声污染现状和噪声污染在区域内的变化情况,为砂光机等多噪声源的现场环境噪声测试提供了新方法

| Abstract: | In order to improve the efficiency of on-the-spot test and accuracy of the data, the authors proposed a new method to set up virtual noise sources based on the noise decay principle. Through this method, we can predict and calculate the noise level around the known points on the basis of the limited real measurement data, then draw the isoline map of propagation of the noise. The process is simple and convenient and the result very clear. Through a comparison of the prediction noise levels calculated by this method with actual values, the authors verify the precision and feasibility of this method. It reflects the situation and change of regional noise pollution in the noise pollution area objectively, and offers a new method for the on-the-spot ambient noise test of many noise sources. |
