摘要
在当今时代，车辆噪声污染已被确定为影响城市区域属性的严重危害。为了识别噪声的影响，噪声图非常有用。通过现场测量，对该地区城市道路交通噪声的传播进行了噪声制图研究。利用计算机仿真模型(Sound- PLAN软件)绘制噪声图。在印度这样的发展中国家，交通构成是多种多样的。这些交通组合包含不同尺寸、速度变化和操作系统的车辆。由于速度波动，车道规则的缺乏，以及在主要车道上未经授权的停车，鸣笛事件变得不可避免，这改变并影响了印度等国家的城市声景。由于喇叭事件(异质交通条件)，噪声水平(LAeq)比均匀交通条件增加了0.5-8 dB (A)。
Abstract In today’s era, vehicular noise pollution has been identified as a serious danger that influence the attribute of the urban regions. To identify the influence of noise effects, noise maps are very useful. A noise mapping study has been carried out to study the propagation of urban road traffic noise in the areas along with field measurements. The computer simulation model (Sound- PLAN software) is used to developed noise maps. In developing nations like India, traffic composition is heterogeneous. These traffic compositions contain vehicles, which have different sizes, speeds variations and operating systems. Because of fluctuating speeds, deficiency of lane disciplines, and non-authorized parking on main road lanes, honking events becomes inevitable, which changes and affects the urban soundscape of nations like India. Due to horn events (heterogeneous traffic condition), noise level (LAeq) increase by 0.5–8 dB (A) as compared to homogeneous traffic conditions.
期刊介绍：
Ever since its inception, Noise Mapping has been offering fast and comprehensive peer-review, while featuring prominent researchers among its Advisory Board. As a result, the journal is set to acquire a growing reputation as the main publication in the field of noise mapping, thus leading to a significant Impact Factor. The journal aims to promote and disseminate knowledge on noise mapping through the publication of high quality peer-reviewed papers focusing on the following aspects: noise mapping and noise action plans: case studies; models and algorithms for source characterization and outdoor sound propagation: proposals, applications, comparisons, round robin tests; local, national and international policies and good practices for noise mapping, planning, management and control; evaluation of noise mitigation actions; evaluation of environmental noise exposure; actions and communications to increase public awareness of environmental noise issues; outdoor soundscape studies and mapping; classification, evaluation and preservation of quiet areas.
