摘要
本文在简要分析道路交通噪声的影响因素的基础上,通过对南京市主要道路交通量与交通噪声调查资料的研究,建立了路边声级简易预测模型,提出了卡车与小汽车等效噪声关系的概念,并给出了经验值。
Based on analysis of the factors affecting roadside noise level,a study has been conducted on the survey data of typical dowtown streets in Nanjing,and a sim。ple predicting model has been established. Moreover,a conception of equivalent noise level between car and truck is posed,and an estimative figure is also presented in this paper.
