The loudest LEAF

Stories from Physics for 11-14 14-16 IOP RESOURCES

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.
