Birmingham's speedway team has been given permanent permission to race at their home stadium.
The Birmingham Brummies initially had permission to race at the Perry Bar track for three years.
They were then given an extra year but told to fit silencers on the bikes to cut down on noise during meetings after complaints from residents.
The city council has now granted permanent permission after deciding the club was abiding by noise regulations.
Council officers had originally advised against renewing the licence, saying the noise was having an effect on the health of people living nearby.
Birmingham City University had also objected, arguing the noise was affecting students' studies.
Brummies manager Graham Drury he was highly delighted.
"But first and foremost I'm highly delighted for the fans, because the fans have supported us up and down the country in the last four years," he said.
His Brummies team has been challenging strongly for silverware at Premier League level this season, reaching the final of the Premier Trophy, and they are likely to be involved in the League play-offs.
