The Irishman and his Parkhead team-mates face Hibernian in the William Hill Scottish Cup final on Sunday.
But the former Easter Road forward claims the National Stadium lacks the noise and passion of other Scottish grounds.
The 24-year-old now says Celtic will have to blank out the silence of the fans if they are to follow up their Clydesdale Bank Premier League triumph with their second trophy of the campaign.
He said: "It's a different atmosphere at Hampden. Sometimes it can go dead with the fans, so we will just have to go out, play our own game and focus on that.
"Can it have an impact on the players? I think it can. When you are used to playing at home at Celtic Park, the fans are noisy for 90 minutes in every game. Going to other SPL grounds, you always get a good atmosphere.
"But at Hampden sometimes it does go quiet and we can't let that (affect us)."
