Question Audio question for changing sounds in a scene according to your position

[qoosh]

There is a scene where I am moving underwater. There is a sound for the wind and rain (above the water) and a sound of bubbles (for being underwater), and I want it so when you move below the water, the underwater sound turns on and the above water sound turns off, and vice versa. Anyone know the way to do this? I imagine it involves a trigger that says when you move below these coordinates, one sound goes off and the other goes on, but if anyone is more technical than me knows exactly how to do it I appreciate it.
