abstract = "Large silencers used in industry usually have a large cross section at the inlet/outlet. Higher-order modes will emerge in the inlet and outlet ducts even at very low frequencies. In this paper, an integral-based impedance-to-scattering matrix method is proposed to convert the BEM impedance
matrix into the scattering matrix for silencer analysis. The integral-based conversion method is compared to the original collocation-based impedance-to-scattering method. Several test cases are presented in the comparison study.",
