【摘要】 对杨陵区交通干道进行车流量和噪声的实地监测,结果表明,区内交通干道平均等效A声级Leq=67.7 dB,符合国家标准。3条典型路段车流量和交通噪声线性相关性有差异,相关系数分别为r=0.75、r=0.92和r=0.41;车流量和交通噪声的变化时间规律性明显。交通干道低频噪声污染严重,已超过65 dB。更多还原

【Abstract】 The vehicle flux and traffic noise were measured in traffic arteries in Yangling.The survey indicated that the environment had reached a national standard,Leq=67.7dB.On 3 typical roads,the linear correlation be- tween the vehicle flux and traffic noise was different(r=0.75,r=0.92 and r=0.41).And the differences showed regularity in different time.The low frequency noise pollution was serious(Leq>65 dB).更多还原
