There might seem to be a hole in the side of this Galileo satellite - in fact its folded solar wings are simply reflecting a noise horn in the wall, about to recreate the deafening roar of a rocket lifting off.
Anyone witnessing a rocket launch will be struck by the noise levels, even when observing from several kilometres away. A satellite on top of its launcher is exposed to much higher levels, of course. So testing is essential to ensure that the satellite structure can withstand such a sustained loud sound.
