Wall of sound

Galileo satellite prepared for testing in ESTEC’s Large European Acoustic Facility. LEAF is the largest sound system in Europe. Nitrogen shot through giant sound horns produces noise of up to 154 decibels, like standing close to a jet taking off. Once the massive door of the LEAF is closed, its 0.5 m-thick steel-reinforced concrete walls serve to safely contain the sound, coated in turn with thick epoxy resin. The chamber itself is supported on rubber bearing pads to isolate it from its surroundings.
