Londoner Chisora, 28, faces veteran champion Klitschko in Munich hoping to pull off one of the biggest shocks in recent years by dethroning the 40-year-old and becoming Britain's eighth world heavyweight champion.
He will do so in front of a hugely pro-Klitschko crowd at the Olympiahalle, while relying on barely a handful of travelling supporters.
Chisora, though, has no concerns about the potentially hostile atmosphere. He said: "We're fighting in his back yard, in Munich, and it will be great.
"Klitschko fans are not that loud, to be honest. They are quite quiet. The Germans are not that loud at fights and I just have to block any noise they do make."
Chisora is a huge underdog after losing two of his last three fights –against Tyson Fury in a British and Commonwealth title clash last summer and Robert Helenius in a controversial European crown scrap before Christmas – but has shrugged off the naysayers' predictions.
"I don't care what people think," he insists. "They a re not the ones who are going into the ring. I am the one who is doing the fighting so I will decide what happens."
