A full-house of over 18,000 fans roared City on to a memorable derby win over Bristol Rovers and Bryan, who netted the winning goal in the televised clash, is hoping to hear something similar against Posh on Saturday.
"They were brilliant throughout the game, singing their hearts out," he said. "When I first ran over to the wing I had earache.
"It was just buzzing and a continuous noise - something I had never experienced before.
"Hopefully they can do that again for the Peterborough game, against a very tough team who are absolutely flying."
Sean O'Driscoll's men head into the clash looking for their first league victory of the season having won three out of three in the various cup competitions.
Meanwhile, defender James Wilson, 24, has on Friday joined League Two side Cheltenham on an initial month-long loan deal.
