Still doesn't answer the question of running the math either
This isn't the thread or forum for a physics discussion using equations, but if you'd like to have that discussion, there's a Science and Tech forum. Given that I set a standard for detection, either by the unaided ear or with the help of a microphone, the movement of air as a result of the propagation of pressure waves should be obvious. But, if for some reason it isn't, as I said, feel free to create a thread and move the discussion over to Sci-Tech, and we can dig into the math, as time permits.
The first point is, his assertion is wrong. But secondly and more importantly, appealing to ignorance isn't an argument that carries any weight to prove a point. Nor does ignorance itself lead to knowledge.
