A Tree Falling

"A tree falling in the forest without ears to hear makes no sound". I have heard this saying a number of times. Now I think that I may have finally understood this saying. When a tree falls in the forest, it only moves air and moves and cracks branches. These send out vibrations. It is only the ears of a living thing with ears that hears. When the vibrations enter the ear canal they are translated or recorded as sounds within the brain of the living thing. So, in a way, you could say that the sounds only happen within the brain of the living creature.
