Abstract
Acoustic models of large industrial plants are built using measurement results as input data and subsequent verification of model calculations. The purpose of the secalculations is to forecasting noise emissions taking into account new installations, sound power level reduction of selected sources or changes in technology, etc. As far as the input data - sound power level - can be considered as independent of the adopted model, then the measurement verification of model calculation already depends on. Calculations according to ISO 9613-2 applies to sound propagation with wind, while the CNOSSOS-EU model additionally enables calculations in isomorphic conditions. This is a valuable opportunity in terms of verification of the measurement model calculations contrived in all directions around the modelled industrial plant. In the case of the ISO model, such verification is possible in inversion conditions or only on the leeward side and with some limitations, especially in the case of large area industrial plants. The paper presents the results of model calculations of a large industrial plant (steelworks) carried out according to ISO and CNOSSOS-EU, which were compared with the measurement results at selected control points around the plant under different weather conditions. Additional sources of errors in industrial noise modelling were indicated, independent of the adopted model - sound power levels of sources, determined on the basis of measurements made in in-situ conditions and emission measurements at control points in the case of disturbances from other installations that are not part of the modelled industrial plant.
