The European Directive 2002/49/EC on the assessment and management of environmental noise aims at a harmonised assessment of exposure to noise in the Member States. It defines them as representations of data describing a noise situation according to a noise indicator, indicating exceedances of limit values, the number of persons exposed. Noise maps are not prescriptive. These are information documents that are not legally enforceable. As graphic elements, however, they can supplement a Local Planning Plan (LDP). As part of an Urban Travel Plan (UDP), maps can be used to establish baselines and target areas where better traffic management is needed. Carried out pursuant to Article 3-II-1-b of the Decree of 24 March 2006, the map represents the areas where the Lden and Ln boundaries are exceeded. — LD (Lden) Sound level indicator means Level Day-Evening-Night. — LN (Ln) Sound level indicator for the night period between 22.00 and 06:00.欧盟《2002/49/EC号环境噪声评估与管理指令》旨在对欧盟成员国境内的噪声暴露情况开展统一化评估。本指令将噪声地图定义为依据噪声指标描述噪声状况、标注限值超标情况与受暴露人数的数据表征形式。 噪声地图不具备强制约束力。此类文件仅为参考资料，不具备法律强制执行力。但作为可视化图表元素，噪声地图可作为地方规划方案（Local Planning Plan, LDP）的补充材料。 作为城市出行规划（Urban Travel Plan, UDP）的组成部分，噪声地图可用于划定基线与需要优化交通管理的重点区域。 依据2006年3月24日法令第3-II-1-b条编制的噪声地图，用于标注Lden与Ln限值边界超标区域。 —— LD（Lden）声级指标：即昼间-晚间-夜间综合声级（Level Day-Evening-Night）。 —— LN（Ln）声级指标：指22:00至06:00夜间时段的声级。
