Actually I was just reading about this last week. Sound does not really exist. It is all just vibration. Brains interpret the vibrations as sound. I read two books last week and I think it was in a book called "The Body" by Bill Bryson. I do remember reading this somewhere else too within the last couple of years but I can't remember the book. I believe it was written by a physicist. It may have been one of Carlo Rovelli's books but don't hold me to it.Who cares?
Nobody, because nobody is around.
Oh, and I trust fysics. Fysics tell me, yeah, there is sound.
You may or may do be aware that the question is posed as a Zen Koan.
