The Vuvuzela produces a loud monotone note that has the ability to harm ones hearing if exposed to the incessant sound of many horns at close range as in a soccer stadium.

The infernal noise from Vuvuzelas at the World Cup games in South Africa made it hard for athletes to communicate with each other or even concentrate during soccer games.
Man has three primal fears: fear of heights, fear of snakes and fear that Vuvuzelas will invade sports stadiums around the world.
