Mountains do make noise when they reflect the sound your prop makes. I took the gp to refer to that. Whether you can use that for collision avoidance, no idea.

There's a few problems with this. For one, your prop noise is going to be almost entirely masked directly ahead of you, because there's a whole submarine in the way. Isolating "sound of our propellers from in front of us" from "our propellers behind us" is certain to be extremely difficult if it's not completely impossible too.
