城市道路交通噪声简易模型

A Simple Model of Traffic Noise Level for the Urban Road

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.
