Bolton manager Gary Megson has failed to impress some of the club’s fans and was jeered following their 1-1 draw with Stoke at the weekend.
“Perhaps it affects some players differently to others, but, yes, we definitely heard it,” Cahill said.
“It’s weird. I try to just block it out and do what I can – it’s got me to where I am now.
“But some of the players find it hard when there’s stuff like that going on off the pitch.
“Maybe it affects their performance. They could maybe take an extra touch and not move the ball on quickly enough.
“We need to get a win here, that’s for sure. Clubs should be intimidated when they come to the Reebok. They used to be – and we need to get back to that.”
