Take the decibel level of a NASCAR race. Combine it with the sound at a heavy metal concert.

That's what CenturyLink Field can sound like for a Seahawks game.

And that's what the New York Jets are preparing for on Sunday.

So coach Rex Ryan had the speakers turned up to max volume and a staffer pumped in music - anything from West Side Connection's "Gangsta Nation" to "Get Right" by Jennifer Lopez - to create the loudest environment possible during practice.

That practice was held indoors Wednesday because of a snowstorm, but made sense under any weather conditions because it's the closest way to simulate what the Jets will face in Seattle; Ryan calls it "a hostile environment" where "the fans are over the top."

He meant it as a compliment.
