World Cup 2010 With Vuvuzela

The vuvuzela, also known as lepatata (its Tswana name) and stadium horn, is a typical 65 cm (2 ft) plastic blowing horn that produces a loud, distinctive monotone (B♭3) note. A similar instrument, known as the corneta, is used in Brazil and other Latin American countries. Many types of vuvuzela, made by several manufacturers, may produce varying intensity and frequency outputs. The intensity of these outputs depends on the blowing technique and pressure exerted.
The vuvuzela is most used at football matches in South Africa. It has become a symbol of South African football as the stadiums are filled with its loud and raucous sound that reflects the exhilaration of supporters. The intensity of the sound caught the attention of the global football community during the 2009 Confederation Cup in anticipation of South Africa hosting the 2010 World Cup, though its frequent usage during sporting events raised health and safety concerns.
