The substantial extension of the offshore wind energy capacities within the German exclusive economic zone along with the presence of several conservation areas for, e.g., marine mammals like the harbor porpoise, led to the introduction of limiting values concerning the underwater sound emission during construction of offshore wind turbines. With that, the development of sound mitigation systems as well as the development of reliable prediction models became necessary. Predicting underwater sound levels in distances up to several kilometers from the construction site requires a propagation model, which is capable of an appropriate tradeoff between prediction accuracy and calculation time. The current work presents a wavenumber integration model, which has been validated by several profound offshore measurement campaigns. The focus of this contribution is on the comparison between modelling and measurement results and on practical restrictions during the validation process.
