The Large European Acoustic Facility, or LEAF, is a sound system so loud, its creators say it can kill you. At 154 decibels, it’s roughly equivalent to having several jet planes take off next to you. The LEAF is owned by the European Space Agency, which uses it to test whether its satellites can survive the acoustic assault of liftoff. Bloomberg Businessweek’s Sam Grobart reports.

Decibel Drag Racing contests reach 180 decibels.
