If a tree falls and you didn't hear it did it fall?

the answer is no it does not make a sound, this is because sound does not exist until someone or something picks it up. nothing actually makes sound, if a tree falls it gives off "VIBRATIONS" and "ENERGY" and that vibration travels for so far, and if it does not reach an eardrum than that vibration never turned into a sound. Humans pick up these vibrations with there ear drums and we take it as a sound, but if an eardrum does not pick it up, its just a lost vibration.

this also applies to a microphone, think of the eardrum as a microphone.
so if a tree falls in the middle of no where and there is no one around to hear it, does it make a sound? no it makes a vibration and an energy.
