Need Help! - Slender teleporting

For my college FMP i am creating a horror like game that is set in a mineshaft. i have managed to implement an AI that follows you around and teleports within a radius if he gets too far away. However, i would like to implement a feature that will add a noise if the AI teleports within the players FOV much like in slender. However, because this is a college project i am stuck to using the blueprints only and was wondering how i could implement this vie blueprints. Any help is appreciated. Thanks in advance!
