The Magpies are still not safe in the Premier League, as they currently sit six points above third-from-bottom Wigan.
Newcastle's poor showing this season is in stark contrast to last season when they were the Premier League's surprise package as they claimed a top-five finish.
"When criticism comes at a big football club like this, you have to be big enough and bold enough to deal with it," he is quoted by the Daily Mirror.
"Whether you're the manager, the player, the chief executive or the chairman, it comes with the territory. I've got absolutely no problem with that.
"There's only one way to deal with it, and that's through performances. Me talking means nothing. This is about the club. This isn't about me. It isn't about any one person.
"We need three points to keep Newcastle United as a Premier League team next season. Then all the plans we have in place can move forward.
Pardew insists that this season has not been a case of the club going backwards.
"You cannot have a season of finishing fifth, like we had last year, without momentum and some good fortune, too," he continued.
"To finish above the teams we finished above - Chelsea, Liverpool - you can't just have a good side.
"The finance we have compared to those two clubs is not even half. We did a marvellous job last year and people might say we over-achieved, but we had momentum.
"When you have a team that has struggled for momentum all year it's difficult to reach those levels.
"Are we as strong as last year? We're not. But in terms of individuals, we can be, quite quickly.
"If we got a great result on Saturday, I wouldn't put it past us to win two more games. But if we lose, then we lose that little bit of momentum we gained at West Brom and suddenly you're fighting again to try to get those three points. It's a different pressure.
"I haven't got to the end of this season yet and you've got to get to the end to understand exactly what has gone on.
"When you throw a blanket across the division, there's not a lot of difference between clubs that have been described as having great seasons and us.
"It's very difficult to assess at the moment with all the problems we've had. That should be done at the end of the year."
