Add to ORKGThe analytical solution for general wall vibrations is presented in the frequency domain. The main idea is to compare numerical and analytical results in order to identify the relevant phenomena and to verify the numerical algorithm employed. For the diffracted waves only an approximate solution has been obtained employing the method of stationary phase. The numerical and analytical solution results are shown to be in very good agreement for various combinations of parameters such as the angular vibration frequency, the length of the vibrating wall segment and the mean flow Mach-number
