摘    要:对北京市典型类别公交车的噪声污染水平及排放特征进行了测试和研究。研究和统计结果表明,北京城市在用公交车的定置噪声排放水平总体处于90~103 dB(A),其A计权频域特征以人耳敏感的中高频噪声为主,对城市居民的环境影响较大,是目前城市内需要重点关注的噪声污染源。相关数据将为交通和环保部门有针对性地提出噪声控制措施和制订相关法规提供有效支撑。

关 键 词:城市公交车  噪声排放水平  定置噪声  频域特征分析

Abstract:The noise characteristics and levels of the representative city buses in Beijing were investigated. The results show that the average level of the noise emitted by the stationary city bus is between 90 and 103 dB (A). The feature analysis of frequency domain on the city bus demonstrates that the bus mainly emits a medium- and high-frequency noise, which influences the people's life and makes the city bus a focus of attention. The results of this work can give the environment management and legislation a strong support.
Keywords:City Bus  Noise level  Noise emitted by the stationary bus  Feature analysis of frequency domain
