Maybe it has to do with where you sit in relation to the speakers. When I sit in my normal seats I notice it because the speakers are right behind us, but I've also sat in the club and lower levels and not heard it.

IMO, what I've heard sounds more like when you're talking to someone on the phone and they set the handset down for a minute for whatever reason. You sort of hear that background buzzing sound but nothing too specific. It doesn't really sound like they are completely blasting the sound of yelling and screaming.
