RESUMO

This paper considers two ways of accuracy increase while simulating numerically the acoustic disturbance transfer on unstructured grids, using the vertex-centered algorithms. Numerical estimation of the accuracy of both techniques is carried out for the example of the numerical solution of the model problem.
