We demonstrate the advantages of using p-version finite element approximations for structural-acoustics problems in the mid-to-high frequency regime. We then present a sub-domain-based a posteriori error estimation procedure to quantify the errors in the setting of a 3D interior-acoustics problem with resonances, and give numerical results. Effectivity indices show robust behavior of the error estimator away from the resonant frequencies. (c) 2005 Published by Elsevier B.V.
