  We propose AeroSPEED, a solver based on the Spectral Element Method (SEM)
that solves the aeroacoustic Lighthill's wave equation. First, the fluid
solution is computed employing a cell centered Finite Volume method. Then,
AeroSPEED maps the sound source coming from the flow solution onto the acoustic
grid, where finally the Lighthill's wave equation is solved. An ad-hoc
projection strategy is adopted to apply the flow source term in the acoustic
solver. A model problem with a manufactured solution and the Noise Box test
case are used as benchmark for the acoustic problem. We studied the noise
generated by the complex flow field around tandem cylinders as a relevant
aeroacoustic application. AeroSPEED is an effective and accurate solver for
both acoustics and aeroacoustic problems.
