“Sound Trigger” is a ambient sound played when a player comes in contact with the trigger box in some parts of the map .

For eg . Jet plane sound in de_train map.

It does not happen randomly, cannot be triggered continuously nor immediately.

Sound triggers can be used tactically like  fake rush or to know the place opponent is hiding.

Sound triggers depend on few things :

• Delay : Time after which sound triggers are played  when player hits a triggerbox(trigger area), These are not played instantly
• Wait: Time taken by a trigger to Reset and play again
