SANTA CLARA -- To a man, the 49ers said Friday that they accomplished what they intended this week and are well prepared to defend their NFC crown against the Seattle Seahawks.

"I feel like our team is ready, excited, prepared to go play this game," coach Jim Harbaugh said. "Unless I drastically misread our team, they're ready to play."

Soon thereafter, Harbaugh and the rest of the 49ers boarded buses for a ride to the airport. Then, it's off to Seattle, where the 49ers will play the Seahawks on Sunday in the NFC Championship Game.

Part of getting ready to play the Seahawks entailed practicing with loud music blaring as a means of simulating the conditions at CenturyLink Field, which is regarded as the loudest venue in the NFL.

Quarterback Colin Kaepernick said things went well all week despite being forced to function amidst all the noise.

"Whether it helps or not, I guess we'll find out," Kaepernick said.

Harbaugh isn't leaving anything to chance. Hence, he heeded the suggestion from team leaders such as running back Frank Gore, linebackers Patrick Willis and NaVorro Bowman and defensive lineman Justin Smith that the 49ers leave Friday.

The 49ers used that approach more and more as the season progressed, with regular-season games in Seattle and Arizona the exception.

"You get a chance to relax, review some plays, just get off your feet," tight end Vernon Davis said. "You don't have to worry about traveling the day before. So, in my eyes, that's a huge advantage for us."
