Loud compressed air is commonly used at various sports events for different purposes. At basketball games, referees often use compressed air horns to signal timeouts or the end of periods. The sharp, loud sound cuts through the noise of the crowd and players, ensuring everyone hears the signal clearly.
In cricket matches, compressed air is sometimes used in fog machines to create special effects during player introductions or celebrations. The loud release of compressed air can also be heard when operating certain equipment on the field. 
Football stadiums utilize compressed air systems for operating scoreboards, timing devices, and sometimes for inflating balls quickly. The distinct sound of compressed air releasing has become familiar to sports fans worldwide.
While effective for signaling, the noise level of compressed air devices has raised concerns about hearing safety for both spectators and athletes. Many venues now regulate the decibel levels of such equipment to protect attendees\“ hearing while maintaining effective communication during games. |
