Audio distance horizontally to be different than vertically?

Hey, I'm making a game that takes place in a school with multiple floors--there are sounds playing on the floors, and I want the distance you can hear it to be big enough so that you don't need to be too close to it. However, when I do this, when you go up a floor, you can still hear it from below. Is there a way to make the range of an audio piece smaller vertically than it is horizontally? Or, in the very least, make it so the player can't hear it when their Y position is higher or lower than a certain point?
