According to the European Directive about Environmental Noise hundreds of noise mapping projects have been performed all over Europe. Experience has shown that many problems arise if these noise maps shall afterwards be used to develop noise reduction measures. In many cases recalculation in detail according to legal requirements produces results that are different from those obtained in the frame of strategic noise mapping. From this experience rules are developed that ensure the general applicability of the developed computer models. The methodologies applied should be accurate, precise and transparent to allow the assessment of possible reduction measures. Pros and cons of typical calculation strategies are presented and discussed. This investigation is based on road noise, but examples are also given related to railways, airports and industrial facilities.
