摘要
许多城市引入了电动汽车作为出租车和公交车。以电动汽车和燃油汽车为研究对象,通过实测数据,分析比较小型电动汽车、小型汽油车以及电动公交车、柴油公交车在不同行驶速度下的最大A声级及频谱特性。为城市交通噪声污染防治提供数据参考。
Electric vehicles have been serving as taxis and public buses in many cities. In this paper, the electric and fuel vehicles are studied. Analysis and comparison of the maximum A-weighted sound level and spectrum of the electric and fuel cars and buses at different speeds are provided. This work offers some references for the prevention of urban transport noise.
