They did send the kid (Tory, I think) to an "SPL Contest" - he got himself learnt...

They did a little report at the "SPL Contest" - that point was mentioned, but not the "possible bowel loss" or "brown note" issue...

In the show, they brought out the facts concerning dB. levels experienced during the contest and what relative dB. levels have occurred during the recent 100 years...The Atomic Bomb had an "SPL" of approximately 240 (?) dB..
Monomer: Your quotes: "A db figure is useless with the frequency it was taken at. /// SPL contests hardly go into the sub-bass region (if ever at all.)
/// Just dont get me going on the watts debate; another useless figure..."
The show made the point that at the frequency that was measured in the MB (16 Hz. w/an SPL of 161.3 dB.), at the SPL Contests, very rarely are any measurements made below 25 Hz., just because human reception of frequencies at, or below, are extremely rare. You feel it more than you heard it.
The measurements they made on the show was a full-scale measurement, due to the fact that the speaker was so large (51" diameter) and the amount of energy that was going to be needed to move it (Probably "measured" in Horse-power, not Watts!
).
The fact that the show is "Mythbusters" and not "Mr. Science" is just for entertainment purposes...more "tongue-in-cheek" than real science. AAMOF, when they do wander down "science-fact" lane, they
warn the viewers that there's some real knowledge about to be imparted their way...
And, when the stated objective isn't achieved, they'll go out of their way to somehow, "skew" the more explosive myths to a fitting end. (Think more "bang" for the viewers' buck!)
ANYWAYS, still a fun show to watch and "learn" from.
BTW, it was Adam that had the goofy T-shirts on - not Jamie. Jamie is the one with the mustache (sp?) and serious attitude. Without him, I think the rest of the cast would be weekly replacements for the dead and maimed on the previous week's show.
Adam is the one with the red hair and trouble-maker-looks and without Jamie, would probably have killed by the first intermission of the first show during the first season. He always appears to be about a teaspoon of gun-powder away from leaving this orb.
