Abstract

Significant differences in predicted noise levels can result, depending on which noise propagation algorithm is used in the modelling. Noise modellers should be aware of the limitations of the models they use. Over the distances involved, no model could be expected to be completely accurate. Still, the differences between the ENM and CONCAWE results seem to be extreme.
