The launch of space rockets creates an extremely loud environment due to the sound waves produced by the rocket engine exhaust, which can cause large vibrations in the components of large satellites with a high surface-to-mass ratio. To qualify large satellites for launch, the extreme acoustic conditions are evaluated. To model the sound radiation from the exhaust plume, specialized methods like the Distributed Source Method can be used. However, numerical approaches like the FEM or BEM are not suitable for modelling the sound environments around the fairing due to the large size of the problem and the need for extensive mesh refinements at high frequencies.
