The confusion results when people assume that the sound waves are the sound.
FIGURE 5. If sound is vibrations, then the falling tree certainly does make a sound, because it produces vibrations in the air. Even if there’s no person or other animal around to hear the sound, a recorder with a microphone could certainly record those vibrations- as sound.
But wait! Sep 22, In June The Chautauquan magazine asked, “If a tree were to fall on an island where there were no human beings, would there be any sound?” 1 This is one of those philosophical questions that can create a lively conversation if asked among the correct group. If a tree falls in the forest and no one is there, does it still make a sound?
Jehookah Jarmon, Gorvenstof, Ukraine It makes the sounds of branches snapping and the almighty thump when the trunk. Yes, it makes a sound, that being a disturbance in the 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.
The physics of this phenomenon are quite well understood, and very independent of any soul being there to hear the treegrinding.barted Reading Time: 5 mins.

Details of relational truth So we see that relational truth is complicated.
Sound is simplified as hearable noise. I am not going to get into the quantum physics that scientists have argued for centuries, but the falling tree does make a sound even if no one is there to.
