Equipping public address systems in stadiums
A problem arose during the planning and technical design of the public address systems. The FIFA technical requirements for the 2018 World Cup public address systems, adopted just a year before the FIFA Confederations Cup (the test championship for the World Championship), required a higher level of audio system than any previous World Championship.
The public address system of a stadium must now be able to transmit any announcement clearly and louder than the roaring of the crowds by 6dB – at no less than 116dB. For previous tournaments this parameter was 105-110dB. This small change actually led to the doubling of acoustic and amplification systems. The challenge was accepted, and OKNO-TV successfully managed the task!
In the Luzhniki, Kaliningrad, Samara Arena, Mordovia Arena and Rostov Arena, our team developed routing systems, automatic cluster volume regulation, and installed systems for the hearing and visually impaired.
