Early in tonight’s Seahawks-49ers game, a group called “Volume 12″ is hoping
that fans set a Guinness World Record for the loudest crowd road in a
sports stadium, as described last week in The Seattle Times.
The target is 131.76 decibels, more than a Boeing 747 taking off.
Fans in the Jet City previously were measured at 112 decibels in a 2005 Seahawks
Here’s a preview:
- As of late Friday, sound engineer Bill Stewart didn’t know where he
would be allowed to set up a pair of measuring devices. He is hoping for either midfield or an
- For some perspective, noise in the stadium frequently reaches 90 dB
during a game, and 110 dB to 115 dB for a touchdown, Stewart said. For
certain other plays, “it certainly goes higher than that,” he said.
- The clearest shot at a record is expected in the first quarter.
Envision the 49ers facing third down, or even a fourth-and-one. If the
game is close, late peaks could happen too. In all, there will be
three measurement attempts, said Phil Robertson, judge for Guinness.
- The Seahawks organization is not actively participating in the
attempt, so those involved think it’s unlikely fans will see
exhortations, or the results, on the scoreboard.
- Any such record is a longshot, because every 10 decibel increase
represents a doubling of force. So fans would need to get four times
as loud as after a normal touchdown.
- The old Guinness record was set by soccer fans in Istanbul. On the
one hand, NFL teams “don’t allow fans to bring in vuvuzelas and other
sound producers,” said Robertson. On the other hand, he said soccer chants
tend to be fairly low pitched, which moves the decibel meter less than
a high pitch, of the kind at Seahawks games.
