Abstract
In the acoustic design of modern sports and entertainment facilities, the development of a set of measures to ensure acoustic comfort conditions in them is based on the consistent calculation of measures to protect against noise and acoustic finishing of the room. At the same time, calculations of noise protection means are aimed at meeting the requirements for sound insulation of enclosing structures and noise control from the operation of engineering equipment. However, even the complete achievement of acceptable noise levels from all these sources is a necessary, but far from sufficient condition for fully ensuring acceptable acoustic comfort conditions in a sports and entertainment facility in terms of the noise load of the public during various events. The analysis of the real noise situation at sports and entertainment facilities of various functional purposes, air volume and capacity is carried out. It is shown that when sports and entertainment facilities are massively filled with spectators, when sports or concert and entertainment events are held in them, the noise background is mainly determined by the so-called “human factor”, which is formed by the active acoustic participation of spectators, athletes, artists and staff during the event. Based on the representations of statistical and geometric theories of the formation of sound fields, analytical methods for calculating real noise levels in closed, semi-open and open sports and entertainment facilities have been developed.
