Turn the question upside down : is it possible for a tree to fall without making a sound ? The answer is no it is
not even if no one is there to hear it or they are but cannot hear it anyway [ human hearing is relatively poor ]

The only places where sound cannot exist is in a vacuum or in space [ they have no air so sound cannot travel within them ]
Then if a tree fell there you would hear nothing but you would be dead in no time at all so the point is somewhat academic
