Evidently the buzzing sound is people blowing into their Vuvuzela's they bought from street vendors. It is so annoying I can't stand to listen to the games.

I would love to have them banned. If not banned at least have ABC/ESPN use active noise control. http://en.wikipedia.org/wiki/Active_noise_control

I have not tried it but for about 3 euros you can download this: http://www.antivuvuzelafilter.com/
