摘要
通过对高速公路交通噪声现场测定与研究分析,结果表明,由于高速公路上行驶的车辆速度很快,致使在高速公路两侧近距离接收点上,当车辆迎面驶来到背离驶去时,交通噪声出现明显的频率漂移和A声级的显著差异,即出现高速公路交通噪声的多普勒效应。
This article researched highway traffic noise on spot, and drew the conclusion that there exists Doppler effect in highway traffic noise. The receiving spot was set near highway either side, While an vehicle run across head on or in the opposite direction, the frequencies of traffic noise in the receiving spot came forth the obvious excursion and Sound Level A significantly differed each other, namely there exists Doppler effect in highway traffic noise.
