its horrible, really kills any atmosphere, I've been watching on mute, which also sucks - real real shame, we only get the world cup every 4 years and its being completely ruined.
in a game the other day someone was booked for playing on after being offside, how did he hear the 120 decibel whistle over the 140 decibel buzzing though? ridiculous. Football is a team game that requires the players communicate with each other, how can they with all the noise? :(
