The public address system at Oxford United's Kassam Stadium may have exceeded the noise limits set as part of a deal with the city council.

Residents complained to the council's environmental health department on the morning of the Parker Pen European Shield rugby final between Sale Sharks and Pontypridd at the Minchery Farm stadium. They were angry that their Sunday morning on May 26 was disturbed by noise from the PA system, which was being tested before the game.

Tony Payne, city council environmental health officer, visited the area on the afternoon of the match and carried out tests to check decibel levels.

Last week, the city council closed down the skatepark at Aristotle Lane, in north Oxford, because activities exceeded permitted noise levels.

Planning conditions limit the stadium's PA system decibel levels to 35 on a Sunday, and in a report to tonight's Iffley Leys Area committee, Mr Payne could report a breach. His report is likely to draw a distinction between noise created by the PA system and the noise of the crowd, which the council has no powers to restrict. The complaint about noise is the latest from residents who have already protested about the lack of operational parking restrictions around their homes.

Tony Stockford, a former city councillor, who lives near the stadium, said a number of people complained about the noise.

He said: "The noise from the PA system in the morning was horrendous. We complained and it was switched off for a while, before coming back on for the afternoon's game.

"Residents fear that events at the stadium on a Sunday could continue. We don't want pop concerts and other noisy events.

"The noise of the crowd wasn't too intrusive, but the music and the announcements were too loud. "We hope big games like this rugby match are a one-off and do not become a regular feature on a Sunday."

Molly Florey, Labour city councillor for Northfield Brook, said: "I could hear the noise well before the match started and I got complaints from residents during the game.

"I love rugby but we have to make sure that noise levels are acceptable for people who live in the area, which includes a lot of pensioners.

"If this continues, the council may have to consider some kind of noise restrictions on match days."

Tony Ashley, Oxford's United safety officer and stadium manager, said: "The club is aware of the noise limits set for the PA system and tries to keep within those limits.

"We did not use our own DJ on the day of the final and that may have made a difference. We have played a lot of matches at the stadium and this is the first time there have been any complaints about noise."
