A method for the acoustic simulation of pile driving is presented using the wavenumber integration (WI) approach, in combination with a recently suggested array of point sources, to represent the pile. The fundamentals of the WI are briefly discussed, as are the main acoustic characteristics of pile driving. A reference finite element model is set up to demonstrate these main features and is further compared to a literature example, to ensure its validity. Subsequently, the obtained results are compared to the solutions from WI simulations on the same example. The results are found to be in excellent qualitative agreement, therefore the WI technique seems to be very promising with respect to the acoustic long range prediction in pile driving.
