If you define sound as a wave of air (or any other medium) particles then yes.

If you define sound as something a person had heard then no.

If a tree falls in a forest and no one is around to hear it, does it make a sound?

I love that. I feel a sense of perspective change that I like. Reminds me to remain vigilant about my sense of play. Losing it happens slow, and yes I have and have noticed.

Little bits add up. I like this one.
