The arena sound system at the NSC Olympiysky and Arena Lviv stadiums is designed to broadcast music programs, voice messages (including emergency ones) to the stands for spectators, to the area of the football field and athletics tracks (NSC Olimpiyskiy).

This system is integrated with a fire warning and evacuation management system.

The system is controlled centrally and remotely using specialized software. To automatically adjust the volume, depending on the level of ambient noise, measuring microphones are installed under the roof. Together, the sound system makes it possible to obtain a uniform sound coverage of spectator seats with high acoustic characteristics.
