The vuvuzelas are going to have a bit less buzz. Host Broadcast Services, the company that provides the feed for the World Cup, said it has doubled its audio filters to reduce the constant blaring buzz of vuvuzelas. TV viewers around the globe have complained that the swarm-of-bees sound from the plastic horns is stinging their ears.
"Despite HBS' core philosophy, which is to provide 'realistic' host broadcast coverage reflecting the ambiance in the stadiums, additional audio filtering has been implemented," according to the daily newsletter given to rightsholders.
The filters also will minimize chants and cheering. HBS said it has increased the level in the sideline ball mics to provide some balance.
