Noise - Noise pollution Provincial roads (etmaal)

Within the framework of the EU Environmental Noise Directive, the noise pollution resulting from traffic on the provincial roads in Gelderland has been calculated. This was done according to the prescribed method SRM2 in the Geoenvironment programme. It is calculated in Lden. This is the average noise level over a period of 24 hours. For the evening and night, a surcharge of 5 or 10 dB applies. The noise level is displayed with contours. The card is classified from 50 dB increased per class by 5 dB. These are calculated noise loads, no deduction has been applied (Article 110g of the Noise Act). This file shows the situation of the year 2021.

本数据集基于欧盟环境噪声指令（EU Environmental Noise Directive）框架，对海尔德兰省（Gelderland）省道交通引发的噪声污染进行了计算。计算工作采用Geoenvironment项目中规定的SRM2标准方法完成，噪声表征参数采用昼夜等效声级（Lden），即24小时周期内的平均等效声级；其中晚间与夜间时段需分别叠加5分贝与10分贝的修正值。噪声水平以等值线形式呈现，该噪声地图以50分贝为起始分级阈值，每级按5分贝递增。本次输出为直接计算得到的噪声负荷值，未进行任何扣除操作（符合《噪声法案》第110g条之规定）。本文件展示的是2021年的噪声污染现状。
