Calculate the frequency spectrum of sound power radiating from a thin/thick plate or shell under the following conditions. (1)you can arbitrarily choose vibrating plate or shell. (2)you are expected to execute modal analysis, forced vibration analysis and estimation of sound radiation power however you can assume any mode shapes or natural frequencies if it will be difficult to calculate exact or approximated vibration modes. (3) you can select mechanical point excitation or sound excitation with arbitrary frequency spectrum of excitation force. (4) you also assume modal total loss factors even if they are constant. (5) illustrate mode shapes with natural frequencies and frequency spectra of loss factors, input power and sound radiation power.
