针对环境噪声三维空间立体化监测与评价,以单体建筑物外墙立面为背景,提出单一点声源对空间立面近场辐射噪声图形表征优化算法:选择4个监测点按非等边四边形构图布设在单体建筑物外墙同一立面,通过同步实时自动监测技术检测出4个监测点声级值,依据声衰减规律计算检测值最大点A分别衰减到B、C、D点声级值的直线距离,由此确定最大声强辐射点O并以O为圆心、以O到四个监测点距离为半径绘出同心圆,以此为描述声场分布基准。
Aiming at the three-dimensional monitoring and evaluation of environmental noise in the three-dimensional space, a single point sound source is proposed to optimize the pattern representation of near-field radiated noise in the space. The quadrangle structure is arranged on the same facades of the external walls of the single building, and the sound level values of the four monitoring points are detected by the synchronous real-time automatic monitoring technology. The maximum value of the detected value A is attenuated to the points B, C and D respectively according to the sound attenuation law Level linear distance, thus determining the maximum sound intensity radiation point O and O as the center, O to four monitoring point distance for the radius draw concentric circles, in order to describe the sound field distribution benchmark.
