摘　　要：系统测量了5辆小型载客汽车分别以20～100 km/h匀速行驶时的车外噪声频谱,得到了低、中、高各频段声压级随车速的变化关系,进一步与城市道路交通噪声频谱相比较,为从声源上控制城市道路交通噪声提供有力的参考依据.Five small passenger vehicles＇ noise spectrum were measured when they are traveling uniformly at different speeds from 20 km/h to 100 km/h,and obtain the dependence between sound pressure of each frequency range and speed of vehicle.Moreover,the small passenger vehicles＇ noise spectrum was compared with the urban road traffic noise spectrum,so that a basis for controlling the urban road traffic noise at the source was provided.

关 键 词：车外噪声 道路交通噪声 噪声频谱
