A procedure which was developed within the framework of a project for the German armed forces (Bundeswehr) to operationally forecast the sound exposure is described in this study. This method includes meteorological influences on the sound propagation. Therefore, at first, different meteorological situations (differentiation regarding temperature, wind speed, wind direction) were classified. For the different classes the spatial distribution of the sound level attenuation was calculated using the model SMART (Sound propagation model of the atmosphere using raytracing). The results were stored in a database. This database is used to forecast the "sound weather" (sound propagation situation). The analysis and evaluation of this forecasts as well as the access to the database is realized using the visualization tool MetaVIS (Meteorological attenuation visualization). Regional sound climatologies, which contain a multitude of different atmosphere conditions over eleven years, are used thereby to evaluate the sound weather as typical or atypical. This procedure enables an operationally applicable forecast of noise exposure. Moreover, with this routine a regionalization of an entire territory in areas with a similar sound climatology is possible. Such estimation was conducted by analysing maps of sound level attenuation for several atmospheric structures. As a result, a map for restructuring the consulting areas of the Bundeswehr, considering meteorological influences on the sound propagation, was acquired.
