How important and deep is this question, initially it was just supposed to be a fun moment here to just relax our minds.
But if you want the actual answers then I would give a scientific one and another of a theological point of view.
The scientific being that yes a noise would be heard in the sense that there is a fluidic medium,air.When the tree falls it causes a disturbance in the air pressure field in the woods and that pressure field emanates away from the fallen tree.
Example:if we leave a tape recorder in the woods,even if someone is not there the disturbances made will still be recorded.
Theological view;a Bible scholar here was The full quote from Dr. George Berkeley, an Anglican Bishop and philosopher in the 1600s, was this: "If a tree falls in a forest and no one is around to hear it, does it make a sound?" The answer, according to George, is that yes, it did make a sound, because God heard.
You have to use another medium to communicate if I am to decode this further.
Can you allow us to go the jokes now?
