These things are driving me nuts, as they sound like a swarm of bees when watching the matches. Hopefully, they will be filtered out in the upcoming matches in South Africa, or at least ban them from the fans.
If you don't know that they are, (from wiki), a vuvuzela, sometimes called a "lepatata" (its Setswana name) or a stadium horn, is a blowing horn, approximately one metre in length, commonly blown by fans at football matches in South Africa.
In any case, USA was lucky to tie against the might England, but a tie is a tie.

As for BANNING them, it was discussed
The vuvuzela came to international attention during the run-up to the 2009 FIFA Confederations Cup and 2010 FIFA World Cup, both hosted in South Africa. The world football governing body, FIFA, wanted to ban the use of vuvuzelas during the World Cup 2010 because of concerns that hooligans could use the instrument as a weapon and that businesses could place advertisements on vuvuzelas. However the South African Football Association (SAFA) made a presentation that vuvuzelas were essential for an authentic South African football experience,[2] and FIFA decided in July 2008 to drop the ban, allowing vuvuzelas at Confederations Cup.[20] President of FIFA Sepp Blatter opposed banning the vuvuzela, saying "We should not try to Europeanise an African World Cup."[21] FIFA ultimately decided to allow the instrument for the 2010 World Cup as well,[22] except for Vuvuzelas being longer than one metre.
