In this bachelor thesis it is shown, how to compute the minimal and maximal potentiality of the generated acoustic power from the scattering or transfer matrix of a linear one-dimensional acoustic element in presence of mean flow. The function for the computation of the ratio of the scattered acoustic power to the incident acoustic power is derived from the scattering or transfer matrix, the amplitudes of the incident Riemann invariants and their phase difference. By a small modification the derived function can calculate the acoustic power ratio from the Riemann invariants at the inlet of an element. The functions are implemented in a computation tool for MATLAB, which is used to investigate some acoustic systems. The obtained results are compared to the analytical solutions.
