Hey kenzan, have you ever seen a person burst a wineglass with their voice alone? I saw it on mythbusters, and I know a few people who have seen it done personally. In no way am I saying this makes the Kiai thing less bullshit, but we dont know if its fake unless it has been disproven.

Does someone have the number for Mythbusters? lol.

Thanks for bringing that up.
You just proved my point that it's bull$hit.
Shattering a thin crystal wine glass (while possible, but which aint easy) with a sustained precise pitched voice is real, but it can only happen under certain conditions.
What you are talking about is called forced oscillation resonance.
You can read about it here:

As we see, you have to know the exact pitch by tapping the glass and basically having a dead-on singing expert make exact the same pitch and sustain it, which doesn't happen every time, even with an expert.

Now, can we do the same thing with the human body?
Theoretically? yes.
Practically? no.
The human body is way more complex, dense, and not at all uniform in static frequency than a piece of thin glass. Add to that that these conditions in the body change from moment to moment as we move and breathe, (especially if fighting) and also add to that the fact that it's impossible for the person "Kiai-ing" (even if he was a mathematical genius) to know all the precise frequencies from moment to moment of which to use, and at what duration to use them in (which would need to be quite long and powerful anyway, much more powerful than the human vocal cords can produce) and frankly, I know for a fact most of you all can out-Kiai this guy without much effort. ~and I haven't heard that any of you have been ringing any temple bells or knocking folks out with your Kiai lately.
As a matter of fact, I've never heard of it ever...from anyone...ever.
But wait!
He's.....Asian....and mysterious....
He must know some stuff!
LOL

Yeah. He knows how to make an idiot of himself and fool others as well.
