Sounds to me like you are saying that whenever a molecule hits the eardrum
on one side another one hits the other side simultaneously? I was talking
about individual molecule impacts here. And no, "molecules rubbing together"
was not mentioned. Molecular motion was.
Again, I am not claiming the statement is true--that the sensitivity of the
human ear being just short of being able to hear the impact of individual
molecules--just that I read that in a textbook years ago.
