Fiji players have prepared for their World Cup opening game against England by listening to recordings of their opponents' fans cheering at Twickenham.
The islanders play the hosts in Pool A on Friday in front of 82,000 fans at the sold-out stadium, which will also host a 20-minute opening ceremony.
Crowd noise was played through PA systems as the team trained in Fiji.
Coach John McKee said: "It was good in those sessions, it affected the intensity of the training. "
He added: "It was the normal crowd noise from Twickenham that was taken off some of the footage."
The Fiji players have spent more than two months together in a summer training camp to prepare for the World Cup.
McKee will select his side to face England on Wednesday, with their opponents already having named their line-up.
