Make my mod use another mod

Hey,

Ok so I'm kinda new to this so I'm seeking for help, I want to create a mod that plays a sound when a procedure from another mod is activated.

What I mean by that is, there's a mod that you have different skills but I want to make my mod play a sound every time one of this skills is activated.

I don't know if that possible if it it please let me know

Thanks.
