摘要：

Purpose - The purpose of this paper is to propose an approach based on Convolution quadrature (CQ) for the modeling and the numerical treatment of impedance boundary condition. Design/methodology/approach - The model is derived from a general setting. Its discretization is discussed in details by providing pseudo-codes and by performing their complexity analysis. The model is validated through several numerical experiments. Findings - CQ provides an efficient and accurate treatment of impedance boundary conditions. Originality/value - The paper suggests a new effective treatment of impedance boundary conditions.
