| 摘 要： | 根据我国国情,提出用较少的优化监测点位形成中粒度噪声地图的构建方法.中粒度噪声地图的形成分为2个环节.一是噪声地图构建系统(平台)的形成,通过离线过程实现;二是噪声地图在线生成,包括贝济埃定义点z值测量、贝济埃曲面(线)调出、地面等效声源反演计算、等效声源的空间声场叠加.

| Abstract: | Combining our national conditions,the formation methods of the medium size noise map was put forward using minimum optimization monitoring points.The formation of the medium size noise map consisted two contents.The one was the formation of noise map construction platform through the offline process.The other was the generation of noise map through the online process,including the z point measurement of Bei Jackie Evans definition,the transfer of the Bei Jackie Evans surfaces(lines),the inversion calculatio... |
