It is a sound unique to international tournaments. The sound of cheers and whoops bursting simultaneously from every bar and residence within ear shot during a match when there are no divided loyalties over which team to support.
As Brazil recovered from going a goal down against Croatia in the opening game of the tournament, with first Neymar scoring with a long range effort, adding a second from the penalty spot before Oscar rounded off the win with a late third, each goal was greeted rapturously.
Inside the Arena Corinthians the yellow crowd went wild, but in the surrounding streets of Sao Paulo the goals were greeted just as manically.
A video uploaded to YouTube records the sounds from a Sao Paulo neighbourhood as each goal is scored. Horns, fireworks and screams fill the air and indicated for anyone unable to be in front of a television (as if they were any!) things were going well for the hosts.
Tonight England play Italy. While there might be strong support for Italy in this particular corner of England it might be worth keeping a window open if you can't be in front of a television set but want to know the score.
