Calculation of the Fan Support Index in the Acoustic Design of Large Sports Facilities

Supporters and fans are an integral part of the emotional and subjective component of the mood of spectators in the stands during modern sporting events at large sports facilities. But each sports facility gives its own unique response to the acoustics of the room when chanting fan chants, depending on the air volume, dimensions, shape and properties of the finishing materials of the room’s enclosing structures. Within the framework of this work, the concept of the fan support index for sports facilities, in particular football stadiums, is considered, an analytical model for evaluating the fan support index is developed. A simplified method for calculating the fan support index is presented, which makes it possible for specialists who do not have special computer software for mathematical modeling of room acoustics to conduct a comparative assessment of the support of this parameter by sound fields created with various configurations of space-planning solutions of large sports facilities, primarily their shape in plan. In accordance with the methodology of this work and the data of comparative calculations of the fan support index, obtained by computer and analytical calculation of the sound fields of stadiums of various shapes in the plan, gradations of quality classes of this index are introduced.
