I dunno, unlike - apparently - you, I'm not an expert on the last few microseconds of the microfluidics of what happens to small volumes of air suddenly evacuated from a hand-sized area under constant compression.
I take it that this means your source for refutation is "Lack of imagination"?
- saberience 3y agoWhy would the air move 1000X faster than the hands are moving? You don’t need air moving at the speed of sound to create noise. I can gently scratch a table surface and create noise and it’s not because of a sonic boom happening. If I gently tap my fingers together slowly in a quiet room I can hear the sound. It’s not a sonic boom clearly. Neither is a sonic boom happening when I scratch my elbow and can hear it.
