Municipal Acoustic Classification

Municipalities have the obligation to adopt and approve acoustic classification plans, on the basis of which the territory is divided into homogeneous areas according to the intended use with relative maximum permissible noise levels. In the map are indicated in yellow the municipalities that have already adopted the acoustic classification plan and in red those that have not yet adopted it. The update of the data is as of 31 July 2022各市镇负有制定并核准声学分类规划的义务，依据该规划可按照用地用途将辖区划分为同质区域，并配套设定相应的最大容许噪声限值。本地图以黄色标注已完成声学分类规划核准的市镇，以红色标注尚未完成该规划核准的市镇。本数据集的更新截止至2022年7月31日。
