Abstract
In this paper, a method based on conventional beamforming for the localisation of point force surface sources in numerical data is presented. The method is designed specifically for numerical beamforming by taking advantage of the freedom that numerical methods provide over methods in the physical world. It delivers source maps with a narrow beamwidth and reduced side lobes directly on the source object's surface, allowing for clear source localisation. The source maps can also be weighted to reveal how an observer would perceive the sources. In addition, it is theoretically shown that the radiated acoustic pressure can be determined from the incompressible surface pressure alone on an acoustically hard and compact surface.
