I've made no such suggestion.

It appears you are reading something other than what I;ve written. Quote me saying such.

You think I'm looking for a *boom* just before the buildings drop ? HA HA.

So your looking for a *boom* way before, or after the buildings drop?

Explain to you? What ? What is the smallest amount of nefarious activity required for, say, WTC 1 ? :)

I'd start with the fully-freakin-loaded 767 you happened to ignore...

Ye gads man. 'pon what assumptions you do base your posts ;)

Not ignored by me in the slightest. Plenty of videos of that event if you require.
 
I thought this might be helpful to our friend femr2.

Why guess ? Depends upon how mental the drummer is, but 110dB is not unreasonable.

A couple of feet from a mic and insignificant to the ears relative to the sound of a hi-hat that mic is *listening to*. All good stuff :)

So, can something producing 140 db be covered up by something producing 110 db?
 
Sabretooth said:
Whoa. You're suggesting that explosives were detonated, the building stood for (x) time, then fell?

Quiet explosives that destroy things a few seconds after they detonate? Do you proof-read what you write?

On December 27, 1983, there was a large propane tank explosion in a warehouse located in the city of Buffalo. The explosion was heard up to 7.5 miles away. You going to have a real hard time explaining to me how an explosion strong enough to initiate a building collapse was quiet enough to not be picked up by recording equipment within 2 miles of its source.

If you're wondering about noise you should be in a tizzy about where the energy came from to completely demolish about 260 floors of steel and cement into rubble.

I'm afraid it's far from that simple.

A hi-hat can produce up to about 117dB, a snare about 127dB, *higher* than a bass drum, yet we can all safely say we believe the bass drum to be louder than an ickle hi-hat. Yet the mic on the hi-hat, a mere couple of feet away from the bass drum, is not going to feed any significant signals to a recording desk of much else apart from the hi-hat itself. Therein lies part of the question.

A known microphone, with known response pattern, in a known location and orientation. A theorised *boom* 1200ft up in the air separated by about a hundred flat *plates*, their effect upon propogation of the wave, and implications for reflection and diffraction, etc...to determine, provably, what the effect is.

Arguing about what may/may not result is pointless. Do the simulation, or do not. I'll mention the problem with stating that *no boom on recording (x) proves no boom at location (y)* as and when folk make the mistake of repeating it, until either I or someone else has done the leg-work. Limiting cases are of most use. Start with the smallest *boom* right in the middle of the tower, right up near the roof, that could sever one of the decidedly skinny columns up there, being picked up by a broadcast quality directional microphone at ground level near the base of the tower. Enjoy.
 
A Controlled Demolition can be heard up to 1/2 mile away with the human ear. Truthers forget to mention that somehow or just ignore that fact. Then again, they miss the point of evidence for a CD on 9/11 because of this fact.

Also a little history lesson:

http://en.wikipedia.org/wiki/Acoustic_shadow

An acoustic shadow is an area through which sound waves fail to propagate, due to topographical obstructions or disruption of the waves via phenomena such as wind currents. A gobo refers to a movable acoustic isolation panel and that makes an acoustic shadow. As one website refers to it, "an acoustic shadow is to sound what a mirage is to light". For example, at the Battle of Iuka, a northerly wind prevented General Ulysses S. Grant from hearing the sounds of battle and sending more troops. Many other instances of acoustic shadowing were prevalent during the American Civil War, including the Battles of Seven Pines, Gaines' Mill, Perryville and Five Forks. Indeed, this is addressed in the Ken Burns' documentary "The Civil War" (produced and aired on PBS, September 1990). Persons nearby would see the smoke and flashes of light but not the corresponding roar of battle, while those in more distant locations would hear the sounds distinctly.

Can any Truther explain why an acoustic shadow can occur and sometimes be heard miles away, while people on the opposite side only saw flashes of light & smoke but heard nothing?

More nonsense. I just called my band's professional soundman and he had a good laugh at that.

Stop being silly. Oh,I forgot,you can't. You are a truther. Try opening a physics textbook

HA HA HA. (That's me having a good laugh).

Where does the energy come from again ?

Don't you think it results from the fact that a load of cranes elevated the mass to create the potential ?

Don't you think the energy to drive the cranes came from somewhere ?

etc.

Read a physics textboox ? :) Funny.

I vote for...the Sun :)

ETA: To stop the inevitable long-winded drone...Gravity is a force (as far as needs explaining here. Potential field.). Have a think about that dafydd.

By all means get him to voice his opinion in detail, rather than an utterly pointless second-hand giggle.
 
I learned elsewhere that the cranes were diesel-powered. Why stop at the sun? Let's cover cosmology too. :rolleyes:

I'm not. Its simple math really.

If something is 140 db, is it capable of being covered up by something that is 110 db?

Yes

No

Copy and paste one or the other. I've made it as simple as possible.

Aren't those type microphones DESIGNED specifically for that very purpose?

Do camcorder microphones have the same design.

Yes

No.

Please copy and paste your answer.

But yet, booms from explosive demolitions are heard and can be captured on video for miles.

How about a simple camcorder microphone that is designed to capture a range of sounds?

Did you see Ashley Banfields' video from GZ during the collapse of 7WTC? It picked up the sounds of the collapse. Why wouldn't it pick up something MUCH louder?

Didn't see the point of going back further than the Sun, but I imagine the point is made. Too many folk say *gravity* when asked *where did the energy come from*, and, well, as I said, gravity is a force (as far as needs delving into here. Potential field.) ;)
