Sound System Simulates the Roar of a Rocket Launch

retroworks writes "Located in Noordwijk, Netherlands, and part of ESA's ESTEDC Test Center, is the Large European Acoustic Facility (LEAF), a sound amplification system 'powerful enough to kill a human being.' LEAF is capable of generating more than 154 decibels, the sound equivalent to standing next to several jets taking off. It is used to blast satellites and spacecraft with sound. Large horns are housed in a sound-proofed room that is 16.4meters tall. One wall of horns stands 11 m wide by 9 m deep and 16.4 m high. LEAF requires all the doors to be closed, operating in steel-reinforced concrete walls to contain the noise. The walls are coated with an epoxy resin to reflect noise, producing a uniform sound field within the chamber."

    You don't die from hearing it, you die from feeling it. So twice as powerful as what it takes to rupture ear drums is in the range of rupturing capillaries in your whole body. Internal bleeding in the brain is a quick killer.
