Noise in agglomerations - Railways - Level grid LDEN - Mapping 2022

The data include the calculation results of the 2022 environmental noise mapping in the agglomerations in Bavaria. These are all cities in Bavaria with more than 100,000 inhabitants, i.e. Munich, Nuremberg, Augsburg, Fürth, Erlangen, Würzburg, Regensburg and Ingolstadt. In each agglomeration, noise was recorded by road traffic, industrial and commercial installations in accordance with Directive 2010/75/EU of 24 November 2010 on integrated pollution prevention and control (Industrial Emissions Directive - IED Directive) and, where available, by tram and above-ground metro transport. The noise calculations are carried out in accordance with the "Calculation method for ambient noise from ground-level sources (roads, railways, industry and commerce) (BUB)". The noise indices LDEN and LNight in dB(A) are used as a measure of general annoyance or as a measure of sleep disturbances.The LDEN level is an emission level averaged over 24 hours, which is determined from the LDay, LEvening and LNight levels for the assessment times day (6:00-18:00), evening (18:00-22:00) and night (22:00-6:00).
Weight factors of 5 dB(A) for the four-hour evening time and 10 dB(A) for the eight-hour night time take into account the increased sensitivity to noise during these times.
The layer represents the noise pollution on tramways and underground lines running above ground in the agglomeration expressed by the noise index LDEN according to the EC Environmental Noise Directive.

本数据集包含巴伐利亚州各城市群2022年环境噪声制图计算结果。涵盖的城市均为巴伐利亚州人口超10万的城区，即慕尼黑、纽伦堡、奥格斯堡、菲尔特、埃尔朗根、维尔茨堡、雷根斯堡与因戈尔施塔特。各城市群内的噪声数据来源于道路交通、工商业设施的噪声监测，监测依据2010年11月24日发布的《关于综合污染预防与控制的欧盟指令2010/75/EU》（工业排放指令（IED指令））；若条件允许，同时纳入有轨电车及地面地铁交通的噪声数据。噪声计算严格遵循《地面源（道路、铁路、工商业）环境噪声计算方法（BUB）》执行。噪声指数LDEN与LNight以dB(A)为单位，分别用于表征整体噪声烦扰度与睡眠干扰程度。LDEN级为24小时平均辐射声级，由日间（6:00-18:00）、傍晚（18:00-22:00）及夜间（22:00-6:00）三个评估时段的LDay、LEvening与LNight声级计算得出。针对4小时傍晚时段与8小时夜间时段，分别设置5 dB(A)与10 dB(A)的权重修正值，以反映该时段人类对噪声敏感度的提升。本图层用于表征城市群内有轨电车及地面地铁线路的噪声污染情况，该污染程度以欧盟环境噪声指令规定的噪声指数LDEN进行量化。
