In this work a novel third-order direct boundary element method for the Helmholtz equation is presented. The methodology is best understood within the context of the so-called ``ยฎctitious eigenvalues diculty'', introduced by the typical direct boundary integral approach; this problem consists of the
Numerical modelling of exterior acoustics problems involving in"nite medium requires truncation of the medium at a "nite distance from the obstacle or the structure and use of non-re#ecting boundary condition at this truncation surface to simulate the asymptotic behaviour of radiated waves at far "e
