基于实测分析车流量与噪声的关系

Based on the measured analysis on the relationship between the traffic flow and noise

通过对哈尔滨市交通量状况、噪声状况进行调研分析,得出了交通噪声在最初阶段呈显著递增的关系,并指出当交通流量达到一定数量后,其递增关系不再那么明显,同时用Cadna/A软件进行仿真对比分析加以验证,为城市降噪技术提供参考。

Through analysis the situation on traffic and noise of Harbin, traffic noise in the initial stage was significantly increasing, when the traffic reaches a certain amount, increasing their relationship is no longer so obvious. By Cadna/A software simulation analysis verified, to pro- vide the reference for the city noise reduction technology.
