Özet

Abstract: The effect of perforated screens and absorbing linings on the sound propagation is investigated using Mode Matching technique. This method is applied for the prediction of transmission loss (dB) for different parameter values of the geometry. Both low and high porosity are considered for perforated screens. In order to show the effect of the tube radius, length of the partial lined part and perforated screen porosities on the propagation phenomenon, graphics are plotted. The results demonstrate the significance of the parameters of the problem in the predictions for transmission loss (dB).
