At least once per home game it seems like the voices inside Bobby Wagner's helmet go silent.

Gone are the voices that relay plays from the sideline to the Seattle Seahawks middle linebacker through a small speaker implanted inside his helmet. And it's not because Wagner's coaches aren't trying.

He simply cannot hear what they are saying, overwhelmed by the noise coming from his home fans.

Everyone knows about the noise that cascades upon visiting teams from the fans at CenturyLink Field and the difficulty all that sound creates. But there is a flip side. It makes it kind of hard for the home team to communicate on defense.
