I saw this article on cnn
http://www.cnn.com/2011/OPINION/02/05/moskowitz.wertheim.super.bowl/index.html?hpt=T2Here is an excerpt:
Crowd support could make a difference. For all the myths in sports that can be unpacked, for all the conventional wisdom that is unwise, here's a truism that's true: The home team wins more often. This is the case across sports. This has been the case for decades. In 44 out of the 45 NFL seasons, home teams won more than half the games played.
True, the elimination of the Cowboys meant that, technically, this Super Bowl would be played on a "neutral" field. But that doesn't mean fan support is evenly split. Five years ago that the Steelers faced the Seattle Seahawks in Super Bowl XL, held in Detroit, a five-hour drive from Pittsburgh; a considerably further distance from the Pacific Northwest.
With demonstrably more rabid fans in the stands, the Pittsburgh players were, perhaps, bolstered by the support. But we think the real differencev -- and, indeed the real cause of home advantage -- was the effect of those partisans on the officiating. Pittsburgh was cited for three penalties totaling 20 yards; Seattle was cited for seven penalties (several highly controversial) and docked 70 yards.
Again, this stands to reason. Psychology finds that social influence is a powerful force, affecting human behavior and decisions, often without subjects themselves aware of it. Psychologists call this influence "conformity" because it causes the subject's opinion to conform to a group's opinion.
Officials are asked to make split-second decisions. One call will earn them the approval of a large group. The other will earn disapproval. Pittsburgh and Green Bay are virtually equidistant from Dallas. But early in the game, pay heed to which team's fans are louder--especially when they react to officials' calls.
.... I know this is about the NFL and I am sure there are other articles out there about homecourt advantage. However, this does indicate that noise level can indeed have an impact on the refs. Keep it in mind when you are at a game!
