单体建筑在点声源环境中对预测点噪声等级的影响

为了提高噪声评价方法的可靠性，减化噪声评价工作程序，实现环境噪声评价自动化，从几何角度分析了点声源环境中，单体建筑随空间位置不同，对预测点噪声等级的不同影响。介绍了用VC 6．0语言对点声源环境中只有单体建筑存在时，预测点的噪声等级进行程序设计的方法及流程，编写的程序操作简单，实现了相关参数输入后(手工输入或从AutoCAD图纸读入)，计算机自动处理、输出结果，通过与外部程序接口调用Matlab，绘制等声级图，结果直观明了。

The impacts of single building on noise level of predict pointed in point-sound-source environment

In order to improve the reliability of noise assessment,to shorten the process of noise assessment ,to realize the noise assessment,the various impacts of single building on noise level of predicted point with different space position in point-sound-source environment is analyzed.The method and process of program design of noise level in single building in point-sound-source environment by VC++6.0 is introduced, and the program operation is easy. After the input (handcraft or read from Auto CAD drawings) of relevant parameters, the program will run automatically,transfer Matlab through the interface with outside program and draw equal noise level map.The result is very intuitionistic.
