Interesting! Presumably you have a source backing up the claim that the article and paper it’s based on are fake?

You think a gentle clap is pushing air around at 343 meters per second?

  Well, not around. The sound of a clap is travelling exactly with the speed of... sound. But not one bit faster, of course.

  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"?

    Why 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.

Try this: do a small clap. Then do a big clap. Now slap the table, chair, or wall you are near. All of them are obviously not sonic booms. QED. You can make sonic booms with bull whips. They are quite a different sound than just slapping and clapping. Check them out on YouTube.

  Just because the thing you hit continues to vibrate and emit sound after it is struck, doesn't mean there wasn't a small sonic boom caused by the air escaping the contact surface.

  And a supersonic plane flying overhead doesn't sound like a bull whip. Therefore supersonic planes are a lie, QED.

For one, I can't move any part of my body at supersonic speeds.

  It's a good thing that's completely not what is being claimed then. I can't move any part of my body at the speed of sound, and yet - somehow - I still manage to produce vibrations that move at the speed of sound.

    It's a good thing that pushing air at the speed of sound is not how you make sonic booms. You need to physically move an object at a supersonic speed to make a sonic boom. So when you cast doubt on the claim that claps do not involve sonic booms you then have the burden of proof to demonstrate that a hand has supersonic motion. Please provide your argument and stop wasting time with pointless rhetoric.

      > You need to physically move an object at a supersonic speed to make a sonic boom. What do you think the object is pushing? “Speed of sound” is relative to a medium, it doesn’t happen _unless_ you are pushing air around. It’s funny, this entire thread is literally “Please provide a source for this claim”, for which you are the one only providing rhetoric.
