Idea for maps regarding searching for monsters.

I think they've done a great job at making it nicer to just go through the maps without trying to constantly look at the mini map. To me that's much more engaging. However I'm still having to do it quite a lot just to make sure I didn't miss this or that bit to avoid back tracking. I was wondering if it might be possible for there to be like a monster noise or something made in a specific direction to clue you in where to go. Maybe a dumb idea but if possible I think that could be really nice.
