Abstract

In this paper, recent developments of the BEM in acoustics to overcome the nonuniqueness problem are briefly reviewed. These include two improved CHIEF methods and the Burton and Miller method using a hypersingular integral formulation. A so-called 'Hyper-CHIEF' method is also introduced in this paper. They Hyper-CHIEF method is simply a hybrid method that uses the hypersingular integral equation in the CHIEF sense. This will allow users to select only a small amount of hypersingular integral equations to be used in the Burton and Miller method.
