AB  - An approach for simulating transient structural wave propagation in loudspeakers is described. The Finite Element Method is used for spatial discretisation and the Laplace transform for the time solution. The accuracy of the spatial discretisation is verified by simulating the acoustic frequency response of a loudspeaker and comparing the results with measured data. A damping model is introduced that approximates standard hysteretic damping and yet can be used directly in both the time and frequency domains. The overall approach is verified by comparing laser measured and simulated results of the transient structural response of a loudspeaker to an impulse like excitation. Finally, structural energy is plotted and discussed.
