某地级市市区主要道路交通噪声污染现状调查

Survey on Traffic Noise in Main Roads Downtown in a Prefectural Level City

  • 摘要: 目的 了解某地级市市区主要道路的部分路段交通噪声的污染现状。

    方法 于2010 年4 月对济宁市4 条街道的部分路段在07:30-08:30、09:00-10:00、11:30-12:30、14:00-15:00、17:00-18:00、20:00-21:00 共6 个时间段进行实地噪声强度监测,对所测结果进行分析。

    结果 以等效连续A声级为参数,交叉路口A昼间平均为81.30~83.20 dB(A),夜间平均为77.12 dB(A),噪声质量指数为1.03~1.11;交叉路口B 等效连续A声级昼间平均为78.55~82.11 dB(A),夜间平均为78.38 dB(A),噪声质量指数为1.05~1.09;交叉路口C 等效连续A 声级昼间平均为76.29~82.34 dB(A),夜间平均为75.56 dB(A),噪声质量指数为1.01~1.10;交叉路口D等效连续A声级昼间平均为83.09~85.23 dB(A),夜间平均为79.18 dB(A),噪声质量指数为1.04~1.13。

    结论 该市4 条主要交通干道各时间段等效连续A声级均超过我国大陆城市5 类环境卫生标准值;52%监测时间段的交通噪声质量等级为恶化。

     

    Abstract: Objective To monitor and study the traffic noise pollution in main roads of a prefectural level city.

    Methods Traffic noise levels were monitored and analyzed in 4 main road intersections during 07:30-08:30, 09:00-10:00, 11:30-12:30, 14:00-15:00, 17:00-18:00 and 20:00-21:00, April 2010.

    Results The average noise levels in intersection A, B, C and D were 81.30-83.20, 78.55-82.11, 76.29-82.34 and 83.09-85.23 dB(A), respectively, in the daytime; those were 77.12, 78.38, 75.56 and 79.18 dB(A), respectively, during the night; and the noise quality indices were 1.03-1.11, 1.05-1.09, 1.01-1.10 and 1.04-1.13, respectively.

    Conclusion The noise levels of different monitoring time at each site exceed the environmental health standards for cities in mainland China, and 52% of the noise levels monitored approach deteriorating grade.
