Murphy, who faces O’Sullivan in the first of Saturday’s semi-finals (13:00 GMT) is looking to claim his second Masters title.
And while he says he can understand some of his 48-year-old opponent’s complaints, it would be better if they were directed to snooker’s authorities rather than the press.
“It is very difficult to follow an event such as the PDC World Championship and it be absolutely crystal clear,” said Murphy.
“There obviously is evidence of a fortnight-long party here, there is no getting away from that but it is an entertainment venue.
“It is an old building, one of our historical buildings that we are proud to visit. Sometimes you have to be careful for what you wish for because we have criticised venues in the past that we no longer go to.
“I think the venue is very, very good. Could it be nicer backstage? Yes of course. Every venue could be nicer backstage. The arena in Swansea [that hosted the Snooker Shoot Out] was unbelievable, state-of-the-art and brand new but we are not suggesting taking the Masters there.
“If Ronnie has criticisms and things he would like to constructively push he should come through the correct channels and make his voice heard.”
