Noise mapping represents one of the valuable working tools in the implementation of communal noise abatement programs. Over the years 1965-1979 the communal noise conditions were mapped in several tens of towns, both in Czechoslovakia and GDR. In Czechoslovakia, noise mapping is based on standardized methodology of noise level measurement and on methodical guidelines for noise map construction; in GDR, unified basis is represented by provisions in execution of the law on environmental protection. The noise map data have led in many cases to revision of existing town development and transportation plans, to more accurate delimitation of urban zones, to establishment of noise-free zones, to prohibition of night-time traffic, and to acceptance of anti-noise measures at stable sources of communal noise. Decisive for the effective use of urban noise maps is, as a rule, the quality of accompanying written statement, the extent of cooperation with town planning and local government authorities, and whether the map had been produced in order to accomplish a clearly specified objective. However, it will take undoubtedly much more time to assess definitively the usefulness of noise mapping as a methodical tool in the control of community noise.
噪声地图是实施社区降噪计划的重要工作工具之一。在1965年至1979年期间，捷克斯洛伐克和民主德国的数十个城镇绘制了社区噪声状况图。在捷克斯洛伐克，噪声地图绘制基于噪声水平测量的标准化方法以及噪声地图构建的方法指南；在民主德国，统一的依据是环境保护法实施中的相关规定。噪声地图数据在许多情况下促使对现有城镇发展和交通规划进行修订，更准确地划定城市区域，建立无噪声区，禁止夜间交通，并在社区噪声稳定源处采取抗噪声措施。通常，对于有效利用城市噪声地图而言，附带书面说明的质量、与城镇规划和地方政府当局的合作程度以及地图是否为实现明确规定的目标而制作至关重要。然而，要最终确定噪声地图作为控制社区噪声的一种方法工具的实用性无疑还需要更多时间。
