AB - <p style="text-align: justify;">A spectral-element method is developed to solve the scattering problem for
time-harmonic sound waves due to an obstacle in an homogeneous compressible fluid.
The method is based on a boundary perturbation technique coupled with an efficient
spectral-element solver. Extensive numerical results are presented, in order to show the
accuracy and stability of the method.</p>
