In the absence of real encouragement, the athletes at the Olympic Games in Tokyo, which begin on Friday, will be exposed to background noise from previous games.
This announced Thomas Bach, the President of the International Olympic Committee (IOC), on Saturday.
The sound system gave the athletes the feeling of being surrounded by spectators.
In addition, the world’s response to the Olympic events will be brought to the stadium.

Applause strengths would be displayed on maps of the world, which the IOC hopes will be a competition among sports fans.
Six-second selfies from fans would be shown.
In addition, selected athletes would have the opportunity to get in touch with their friends and family members live.
"We don't want the athletes to feel alone in the stadiums, they should know that there are many people supporting them," said Bach at the press conference that followed the meeting of the IOC Executive Committee.
Bach confirmed that the Korean delegation had to remove banners with which they had decorated the balconies of their quarters in the athletes' village at the instigation of the IOC.
The inscription was reminiscent of a naval battle in 1597, in which the Korean fleet defeated the Japanese, although it was clearly in the minority of boats.
