The calculation of singular integrals arising from the boundary element method (BEM) by Gaussian quadrature is discussed. The singularity studied is \(K_{0}(cx)\), where \(K_{0}(cx)\) is the fundamental solution of the modified Helmholtz equation. Comparison with other methods is done by numerical examples.
