World Cup organizing committee head Danny Jordaan Sunday did not rule out banning vuvuzelas, the noisy plastic trumpets whose incessant din has proved a hit with fans in South Africa but drawn criticism from television viewers and players.
"We heard from the broadcasters and individuals and it's something we are evaluating on an ongoing base," Jordaan said.
When asked about banning the trumpets, Jordaan told the BBC it could be considered.
"If there are grounds to do so, yes," he said.
The sound of the vuvuzela - described by South Africa tourism site safrica.info as "a beautiful noise for the beautiful game" - has not been music to everyone's ears.
