In order to test its satellites’ resilience to the noise of launch, the European Space Agency has built the Large European Acoustic Facility (LEAF). The facility has walls made of steel-reinforced concrete, 0.5 m thick, and contains noise generators which can produce sound of up to 154 decibels. The ESA reports that no human could survive hearing the system at maximum output.
