The noise levels emitted by a given infrastructure over an average day are assessed using numerical models producing isophone curves translated into noise zones, according to the recommended index for all modes of transport at European level, i.e. the Lden index and the Ln index. Strategic noise maps aggregate or translate these noise zones according to the type of strategic noise map, i.e. noise exposure maps, noise-affected sectors, limit value exceedance maps, and known or foreseeable noise level change maps本数据集采用数值模型评估特定基础设施在日均工况下的噪声排放水平，通过生成等声级线（isophone curves）划定噪声分区；评估依据欧洲层面针对所有交通方式的推荐指标，即Lden指数(Lden)与Ln指数(Ln)。 战略噪声地图将根据地图类型对上述噪声分区进行整合或转换，具体涵盖噪声暴露地图、受噪声影响区域、超标限值地图以及已知或可预见的噪声级变化地图。
