AI sounds walk, run, attack

When I add sound to a walk animation using notifies I hear all AI walks at the same volume while they are at different places in the map which is so annoying .
How can I make the AI walk sound based on the location. So the player hears AI walking far at long distances or hear the walk close when AI is near him.

Use the Play sound at location node and use the actor location.

Thanks. That solved it.
