The Large Hadron Collider (LHC) at CERN is a high-energy particle accelerator in a 27 km long tunnel located in the underground of the Geneva area, Switzerland. Protons are accelerated to 99.9999991 percent of the speed of light before they collide with a total momentum of up to 14 TeV. It is the largest machine that human mankind has ever built. Over 10.000 sensors monitor the state of the LHC during operation. Recently, microphones have been added as an experimental setup. An acoustic monitoring system to detect and localize beam accidents is under current investigation. Such a system may reduce expensive downtime dramatically in an accident scenario. The acquired signals can also be used for other applications, e.g., sonification, media art installations, etc.
