The vuvuzela is a plastic horn about 65 centimetres (2 ft) long, which produces a loud monotone note. This horn has become a symbol of South African football as the stadiums are filled with its sound.
The intensity of the sound caught the attention of the global football community during the 2010 FIFA World Cup which was hosted in South Africa. The use of the vuvuzela at football matches has been banned in many countries but here it is still very much alive.
You cannot say you have been subjected to noise until you have sat in a stadium with a couple of thousand spectators blowing these things non-stop. Believe me, it is something to experience, just make sure you have got your ear-plugs with you.
