Is that constant buzzing noise during the FIFA World Cup matches doing your head in yet?
As football fans are learning, the sound isn't coming from a swarm of angry bees or locusts, that buzzing is apparently a "musical instrument" (of sorts).
South African fans are used to the colourful plastic horns known as Vuvuzelas (or Lepatata in the Setswana language), which they say sound like a herd of charging elephants. The stadium horns are about a metre long, and produce an annoyingly loud high-pitched noise which many people say is drowning out the usual singing and other match atmosphere.
The vuvuzelas have been slammed by everyone from the international footballers, through to the visiting fans, and the broadcasters trying to cover the matches at the FIFA World Cup in South Africa (who say it drowns out the commentators).
Soccer fans have described the noise from the horns as "mindless" and "excruciating", with petitions and Facebook groups being set up calling for them to be banned at the event.
However Fifa president Sepp Blatter claims the vuvuzela-haters just don't understand African culture, and he reckons it adds to the atmosphere in South Africa.
For the technically minded, the droning sound can sometimes be reduced or cancelled out on modern TVs, by adjusting the sound settings to drop a specific frequency. You can even buy an 'Anti Vuvuzela Filter', which claims to cancel out the sound of the horns.
