Being that our veracious perps "didn't care much" for doing things traditionally these are some of the symptoms that would have been anticipated from the effects of such devices (including the massive hush-a-booms capable of hurling massive 9 ton beams):

Truthers say they have 118 witnesses to loud demolition explosions. Just curious as to how many of those exhibited primary, secondary, or tertiary blast injuries from their close proximity to such devices? Like Mr Willy from the basement, or those who survived the collapse of one of the towers within the stair well?
How many witnesses suffered
noise induced hearing loss? from their close proximity to these blasts? Why does not a single one of these 118 witnesses report such symptoms. Better yet why not
more than 118 people? (Forget for a moment that many of these people were either disingenuously quote mined/similes and metaphorical statement were taken hyper literally)
I combed what medical and trauma literature I could find for writeups of barotrauma from 9/11 back in 2007 (here's a post combining my findings and T.A.M.'s response - he's an MD, by the way - into one:
http://www.internationalskeptics.com/forums/showpost.php?p=3244833&postcount=267). I compared what little I found - and believe me, it was
little - to events like the Madrid bombing and the Israeli bus bombings. Believe it or not, there are instances recorded in NY on that day. Thing is, they're few and far between, plus they're not indicative of the severe sorts of barotrauma seen in those other, smaller bombings. In the Israeli bombings, for example, you find many reports of what's called "
pulmonary contusion", and severe cases to boot. Israeli doctors characterized the resultant chest x-rays of victims suffering such contusion with the description "butterfly pattern" to teach other doctors to recognize it, but the term also illustrates the extent and severity of the damage. Contrast that to what few reports were written up about the NY event for journals: A firefighter with a single burst eardrum, a rescue worker with the same, etc. While there's no single study examining the nature and extent of barotrauma after 9/11, that in and of itself is telling when you take into consideration the articles you easily find in Google Scholar on Israel's and Spain's events.
Now to be honest, there are characterizations of injuries which may in the end have indeed been barotrauma. You can read that post from T.A.M. I linked above for reasons why they could have been missed, but if you look at an article like this one:
... you'll see some descriptions of pulminary distress, eye injuries, etc. that may indeed have been caused by blast effects itself. So to be honest and above board, there may indeed be cases there.
But again, I'm struck by the utter lack of writeups on this, and the relative abundance (Emphasis: "
relative"; it's not like there are hundreds of papers) of studies specifically mentioning and studying barotraumatic injuried induced by bomb blasts (One example:
Link). Why is there such a lack? We can reason out the answer to that.
Does this disprove explosives? By itself, no; it's not strong enough to stand on it's own. But in conjunction with other lines of evidence - the lack of explosives remains in the debris, the lack of explosions in the video recordings, the lack of reaction from the K9-units combing the debris, the lack of reports from the NYPD Crime Scene Unit investigators, etc. - it's very telling.

And not to belabor this, but: As yet another point that's relevant to what you wrote, I also invoke Pasquale Buzzelli, a survivor from Stairwell B in the North Tower.
As I've said before, if you trace where he was at when the towers collapsed on him and note the proximity of the stairwells on those floors to the core columns, then you have to ask why wasn't he taken out by the supposed explosives? Don't tell me that the wall between him and the column was
that strong. Anyway, you see my point in this, right? It's yet another instance of a real world detail disproving the explosives charge truthers put forth.
