If a tree falls in the forest and no one is around to hear it does it make a sound What is ONE possible argument someone would make to agree OR disagree that a sound is indeed made?

Someone who agrees that a sound is made could argue that sound is a physical phenomenon that occurs regardless of human perception. The tree falling creates vibrations in the air which would be interpreted as sound waves if there were an observer present. Someone who disagrees might argue that sound is a subjective experience that requires an observer to perceive it. Without a listener to interpret the vibrations as sound, the falling tree may not technically produce a "sound" in the absence of human perception.
