The energy boundary element method is a numerical prediction method for acoustic high-frequency problems. By employing averaged energetic quantities as primary field variables, it allows for an almost frequency-independent discretization. In the present work the method is enhanced by an isogeometric formulation, where both the geometry and the boundary values are described using non-uniform rational B-splines (NURBS). In addition, the method is implemented as a fast multipole method, thus achieving a significant acceleration while simultaneously reducing the memory consumption.
