A noise map is a cartographic representation of the noise level distribution in a determined area and period of time. This article presents the most important aspects of the noise mapping project across Santiago, a city of nearly six million inhabitants. The study was performed employing limited information and a low-cost, vehicular traffic noise predictive model. The methodology applied to the Chilean experience can also be used to create noise maps for major cities. An evaluation of noise prediction models, considering simplifications of the modeling environment (buildings) and for the vehicular traffic flow rates attributed to the streets under study, was made. The noise levels were modeled according to recommended exposure values for the above area. The results revealed that the noise levels for the city of Santiago were high in a relevant percentage of the surface.
噪声地图是在特定区域和时间段内噪声水平分布的地图表示。本文介绍了在拥有近六百万居民的圣地亚哥市进行噪声测绘项目的最重要方面。该研究使用有限的信息和低成本的车辆交通噪声预测模型进行。应用于智利经验的方法也可用于为主要城市创建噪声地图。评估了噪声预测模型，考虑了建模环境（建筑物）的简化以及归因于所研究街道的车辆交通流量率。根据上述区域的推荐暴露值对噪声水平进行了建模。结果表明，圣地亚哥市的噪声水平在很大一部分表面上都很高。
