摘要
针对国内外常见的道路交通噪声预测模型中的单车噪声排放模型进行对比研究,详细分析模型的结构与特点:7.5 m处噪声大小、不同类型车辆噪声的差别以及车辆加速状况与匀速状况噪声的差别,并对我国的道路交通噪声预测模型研究提出建议。
A comparative study on noise emission models of an individual vehicle, which is a significant part of road traffic noise prediction models at home and abroad, is conducted. Those models are analyzed elaborately in the following aspects： structure and characteristics of these models, noise emission at 7.5 m distance, noise emission difference of various vehicle categories, and noise emission difference between accelerating and steady running conditions. Some suggestions for research of prediction models of road traffic noise in our country are proposed.
