Put simply (or as simply as can be), an LHC “jet is made up of lots of cells containing energy deposits and each cell has an energy, a distance and an angular distance (dR) associated with it; so each cell can be heard as a separate note in this example.” Video after the break.

The sounds reduce in density very much towards the end, with isolated events separated by silences of several seconds.
