"The biggest revelation, however, will occur at kickoff time: Even though Levi's Stadium will have about 1,000 fewer seats than Candlestick, it will be much louder. During a tour earlier this year, project co-director Robert Rayborn pointed out something that I had not even considered. "It's going to be really loud in here," said Rayborn, who works for Turner/Devcon construction. "Really loud. Really, really loud."
Then he explained why. The stadium's design is different from most football stadiums. The vast majority of luxury boxes are located in an eight-level tower -- essentially, a 12-story building -- on the west side of the field. That means two things: One, there are no upper decks on the west side, just the lower bowl and the tower. And two, the east side upper decks can be closer to the ground -- because it does not sit atop multiple levels of luxury boxes.
Perhaps that's a bit too architectural-geeky. But the practical ramification is this: All of those fans on the east side of the stadium (who are closer to the field than at Candlestick) will scream noise toward the field and the west side of the stadium. And when that noise hits the large flat side of the tower, the noise will immediately bounce right back toward the field. Jed York, the 49ers CEO and stadium overseer, agrees the net effect should be a cacophony of howling.
"It should be louder than Candlestick, for the reasons you point out," York said. "I don't know how loud it will get, though." My prediction: As loud as Seattle or Kansas City, the NFL's two loudest outdoor stadiums. And I'm not even accounting for how loud the 49ers will decide to crank up the stadium sound system with new state-of-the-art speakers. In Seattle, as ordered up by rock fan owner Paul Allen, the tweeters and woofers are deafening.
