Adding sounds- How do I do it?

[jamsk8r]

Okay, my dilemma is this:

 

Im wanting to add sounds to fallout 3 to go with the nanosuit, that are triggered by in-game happenings, for example:

 

I want to add the "Threat detected" sound when red ticks show up on the compass

 

"cloak engaged" for when i activate stealthboys

 

ya know, stuff like that. I have the sound files, but how would i accomplish my goals?

 

Any help is appreciated!
