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。

关 键 词:车外噪声  道路交通噪声  噪声频谱

Abstract: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.
Keywords:vehicle noise  urban road traffic noise  noise spectrum
