Fake crowd noise caused a very real headache on Wednesday for those living near Arizona Stadium.

The University of Arizona Police Department received numerous noise complaints from surrounding homes during the UA football team’s two-hour practice inside the stadium. Wildcats coaches pumped in crowd noise, complete with tape of a public-address announcer, to replicate the gameday atmosphere in their final full-bore practice of the regular season.

The Wildcats will take on No. 13 Arizona State on Saturday in the annual “Duel in the Desert” game.

The noise blared from about 3:30 p.m. to 5:30 p.m. Arizona coaches capped practice by piping in Phil Collins’ “In the Air Tonight”.

UA coach Mike Stoops admitted the workout was filled with “a lot of noise,” but said the sounds help his team prepare for hostile road environments. Arizona State officials are expecting a sellout for Saturday’s rivalry game.

“We just want to make sure we’re prepared offensively — our communication, our signals, our cadences, all that stuff — in case it gets loud,” Stoops said. “You have to be prepared for it.”

Still, Stoops chuckled when asked about how loud he expects Tempe to be.

“I hope it’s not that noisy,” he said.
