The European Directive 2002/49/EC on the assessment and management of environmental noise aims to assess noise exposure in a harmonised way in the Member States. It defines them as data representations describing a noise situation according to a noise indicator, indicating exceedances of limit values, the number of people exposed. Noise maps are not prescriptive. They are information documents which are not enforceable at the level of law. As graphic elements, however, they can complement a Local Urban Plan (PLU). As part of an Urban Travel Plan (UDP), maps can be used to establish baselines and target areas where better traffic management is needed.《欧洲议会和理事会关于环境噪声评估与管理的指令（2002/49/EC）》旨在在欧盟成员国范围内以统一协调的方式开展噪声暴露评估。该指令将噪声地图定义为依据噪声指标描述噪声状况、标明限值超标情况以及受噪人群数量的数据表征形式。噪声地图不具备规范性效力，其属于信息类文件，不具有法律强制执行力。不过作为可视化图形元素，噪声地图可作为地方城市规划（Local Urban Plan，PLU）的补充内容。作为城市出行规划（Urban Travel Plan，UDP）的组成部分，噪声地图可用于确立基线以及需要优化交通管理的目标区域。
