You'll need to toss in a "trigger once when true" condition. (System object)
Each second of game play has around 60 frames of game play (Actual numbers can vary).
Each frame, your game goes through your whole event list
This means it checks to to see if your conditions are true around 60 times a second
If your events don't limit how often they activate, they will rapidly repeat
In this case: creating a rapidly repeating sound.
P.s.: You don't have to make a separate condition for both Frames 4 and 10
You can write
On animation frame: 4 or 10
