This happens exactly the same in volleyball. There are the almost perfunctory whistles for all the regular things like out of bounds. Then there are the stronger whistles for when someone makes a net fault and it interrupts the game flow. The quick double whistle to get the attention of the players. Then there is the boldness and the number of whistles which signal the seriousness of the infraction. Or the “come on, quit stalling” whistle. It is such an awesome compact language. I’m still sad I never learned to use my fingers to whistle.
