Sounds should ebb and flow like tides with the fortunes on the field. That adds to the drama. Fans reacting with their voices to action on the pitch, to events in the stadium and to each other's sounds, songs and chants are part of football's theater.
A sudden crowd silence can also tell a story - perhaps of the heartbreak of a late, defeat-inflicting goal or of the collective shock of seeing a player horribly injured by a bad tackle. Sometimes, you should even be able to hear a coach bark orders from the touchline or players shouting at each other for the ball.
There are stadium sounds other than vuvuzelas at this World Cup - just not enough of them. They are being bullied into submission by the trumpets' never-ending screech....
In Rustenburg there were scattered unison chants of "In-ger-land, In-ger-land," a few bars of "God Save the Queen" and the occasional "USA! USA!" when England played the United States on Saturday night. But vuvuzelas ultimately won the battle of the bands. They and the result - a disappointing 1-1 tie - silenced England's fans, who usually are among the best-drilled noisemakers in football.
They take their singing seriously, with chants that are cheeky, taunting and often just insulting. But at least they are inventive, too.
The same cannot be said of vuvuzelas. They are simply mindless. Their pitch doesn't change, just the intensity. Blow hard. Blow soft. The only range is from horrifically loud to just annoyingly so. Because of that, we absolutely could not hear the rich African voices of Ghana fans who sang lustily Sunday at the Loftus Versfeld in Pretoria, vibrantly clothed in their national colors of green and red. What a shame.
