This is a "does the tree make a sound" argument, and I'm on the, "no it doesn't" side, due to using a definition of "sound" that means "the representation of audio waves within a human nervous system". You are on the "of course it makes a sound" side, because your definition of sound is "pressure waves in the air."

I've been trying to be on the "it depends on your definition and my definition sits within the realm of acceptable definitions" side. Unfortunately, whether this is what you intend or not, most of your comments come across as though you're on the "it depends on the definition, and my (PJ's) defintion is right and yours is wrong" side, which is what seems to be getting people's backs up.
