Offshore wind energy is evolving worldwide. Very often, impact-driven monopiles are used as foundations for offshore wind turbines. However, driving piles into the seabed causes very high underwater sound pressure levels, which might endanger animals living in the sea. Therefore, several prediction methods for the occurring underwater sound pressure levels from pile driving have been developed in the past years. Furthermore, different noise mitigation systems exist to decrease the noise emission into the water. Additional knowledge of the sound source, i.e., the driven pile, would simplify predictions and help the development of impact hammers or piles emitting less noise. The present paper applies findings from the theory of axisymmetric vibrations of cylindrical shells as well as their sound radiation to the field of offshore pile driving.
