Which philosopher wrote if a tree falls in the forest and no one is around to hear it does it make a sound?

yes if a tree does fall in a forest it does make a sound because it is not a vacuum (where few or no particles are ; space) the air around it has matter and a medium so the compressions and rarefactions travel through a medium and create sound waves and the tree vibrates so the answer is yes if a tree falls in a forest it does make a sound.
