With regard to the pumping in noise BS, some hella smart somebody here wrote up a brilliant rebuttal (I think it was Hans, but I don't remember). Basically it's the *frequency* of the noise we broke the Guinness record with; there is no speaker in existence that can make noise at that kind of db at that frequency, and in theory if there was, it would be almost as big as the stadium itself (so kinda hard to hide).
So really... Haters are just gonna haveta keep hating, cuz there ain't a damn thing they can do about it.
