The use of a whistle in sports officiating serves a crucial purpose for maintaining order and fairness. It signals the beginning and end of plays, fouls, or infractions during competitions, ensuring that all participants and spectators are aware of gameplay changes. The whistle provides a clear auditory cue, allowing the officiating team to effectively manage the game. Additionally, a whistle creates a sense of authority and respect for the official’s decisions, essential for the integrity of the sport.
