Full Version: Explosions Sounds?
Pilots For 9/11 Truth Forum > Location > World Trade Center Complex

We all know of the many eyewitness close to the building hearing explosions,
Why cant we hear the explosions on the videos of the collapse,
and also how far away could people hear the explosion from ?
lunk
I'm guessing, but most cameras are equipped with condenser microphones
which tend pick up quiet sounds better than louder sounds.
And the sharp sound of an explosion would be echoed and blurred
by adjacent buildings and distance.

"Though video clips of the collapses can be found all over the internet and on video releases, most people will not really hear evidence of explosions on the available footage. What most people would describe hearing from the available media is the "roar" of the buildings coming down. The main reason for this is probably because there is not much actual audio content available of the events. Most angles of the collapse are presented without any sound other than that of news anchors, reporters, interviewees, narrators, etc. speaking over-top. It is the preferred style of news-media to constantly have human voices "giving shape" to history as it unfolds. Creating meaning rather than reporting facts.

Some examples of video footage which includes audio can be found and this audio does include evidence of explosions, though it is not generally obvious for a number of reasons. Sounds of intense volume recorded at close distances will tend to overload and be distorted by the time they make it onto tape. If a very loud sound such as an explosion overloads the camera's sound circuitry and is followed very quickly by subsequent loud sounds, the individual sounds will be more difficult to identify because the shape of each sound, the attack and decay, will be masked as the audio circuits are completely saturated with signal. Results will vary depending on camera type, microphone type, specific settings, and proximity to the event. Some angles of the collapses are cut very short so they start playing only after the initiation of collapse sounds, perhaps because some videographers did not capture the first moments on tape or as a result of the news tending to only focus on the "juicy" bits in their presentations. Another problem with internet videos is that when there is sound, it is usually missing a lot of information and/or is distorted from various forms of data compression and/or sloppy transfers. Another problem with internet video in terms of close scrutiny can be audio which is encoded or played back slightly out of synch with the picture."

A: Hoboken, New Jersey, ~3.5 Km away

"With an approximate distance of 3.5 Km [footnote: map], it is the lowest frequencies which would tend to show evidence of explosions. An important aspect to this footage is the relatively quiet and unobstructed space between the towers and the camera. Furthermore, blast sounds which travel over water tend to be much less attenuated than those which travel over the ground [footnote]. The explosions are very audible though headphones or a decent full-range speaker system are needed to hear them. "

D Mole and Swing -

Thanks for the links above. They provided some new information that I had never seen before.

I thought this one about the early FBI truck bomb in basement theory on 911 was interesting:

If you comb through some more of those videos, you will find that even the mainstream media were reporting massive explosions before the towers collapsed.

I think you saw on one video that the FBI thought a truck bomb was in the basement and other media reports suggest that local authorities as well as the FBI believed that scenario. That report from USA Today news was also confirmed by NBC reporters in another video.

On CNN for example in that clip, the reporter essentially states that explosions from devices in the basement of the building triggered the collapse. Sometimes in the early part of an event such as this, the truth slips out before the filtering machine of disinformation, propaganda, and the cover story takes place.

They were heard in the general vicinity of the complex, especially 3 huge explosions before the SouthTower collapsed. So these huge explosions were taking place before the collapse even began which negates the pancaking floor excuse. This is what led to some reporters suggesting it was these explosions that triggered the collapse and was the final straw so to speak.

Why can't we hear the explosions on the video? This is a great question, unless you consider where the local news reports were placing the location of the explosions: deep into the basement/sub-level area of the tower's complex. 6 stories below ground may muffle the signature of an explosive device as maybe the case. Edited video be it for nefarious or harmless purposes may have removed the actual sound of explosions as well.

Good luck at the govt loyalist site. I got so tired of debunking the junk those guys spews and proving them wrong over and over again. Don't waste too much time there, it just isn't worth it. cleanup.gif

I have watched this and i have to say I'm a little bit skeptical on some of the sounds. At the very end of the last "Explosion" sound...you can see on your left hand side...if you look quickly..there was falling debris. I'm not saying that not all of the sounds being heard were not explosions, but i do think there's a possibility that some could have been debris/jumpers falling as well.

Listen to this, there are a number of low rumbles before the South tower collapse:

http://www.mediumrecords.com/wtc/southtower.hoboken01.aif

If you can watch it through a graphic equalizer thingy you can clearly see enormous explosions taking place in the base frequencies. There is also a noticeable delay between the time that the girl on the rooftop sees the collapse, and the sound of it, in the recording.

Well that gets into semantical territory about what "authentic" and "is" are- and I'll leave that for a Clinton or for my attorney. wink.gif IMO the sounds in the Naudet video(s) that I linked above (around post #3) and were clearly filmed while WTC2 was still standing are not consistent with the "soundtrack" spliced over this more recent [subedei's] video:

http://www.youtube.com/watch?v=huTRMWSQA3o

"More recent," from post #11 [NOT Naudet footage]


Do I really need to re-emphasize the credibility "weight" that I assign to most internet video yet again? Several of the firefighter testimonies are fairly compelling, since they were in Manhattan on that fateful day, especially when coupled with the "suppression" attempts of said testimony.

is there any way of filtering the audio,like this guy claims to have done to get louder sounds to be more prevelent than people speaking into microphones.

The process is called audio normalization, and I would have expected this "guy" who analyzes and processes/produces audio and video to know that term- it's a function built in several of my audio software programs, going back to the 1990s IIRC.

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

The problem with adding amplitude/"energy"/data to an audio signal is frankly that you are adding data to the signal (modifying it from original). The Wiki thinks otherwise, but Wiki users beware.

Also, I haven't produced any internet videos, so I'm not sure which "my one" you mean. You could try to contact the Naudet brothers or check with the author of the pages that I linked. Those NYPD firemen in the Naudet video certainly appeared to be reacting to something explosion-like multiple times, something very like HE blast damaged the lobbies, and the Jim Gartenberg interview thread already in this forum supports "the core blown out."

At 9 seconds, a huge explosion heard from across the river, another at 13 seconds, and at 19 seconds, and more during the collapse. The antenna starts to drop at 16 seconds as the core structure is shattered.

Dude im not a debunker or anything smile.gif , im interested in how they managed to blow up the towers with reduced sound, thermite jets can break apart concrete and just about anything so its one theory .
But then you have the Eyewitness reports of explosions, and why they couldnt be heard on video except for a few videos pre collapse
and the hoboken vid

im also interested in how new yorkers would react to hearing explosions across the city was their instinct bombs or pankaking floors

"Sorry for the lost comments, I had to edit the video because discovery added something in the beginning, that has been stripped away now.
Some people mention the silence of the twin tower collapse. These sound samples are genuine as far as I know. Notice that in the videos that contain the initiation moment the rumbling sound is already there, even when there is barely motion."

Here are two very good eye/earwitnesses to the lobby damage (not sure which tower, but they say repeatedly "the first building" or plane), from ABC7 "live" footage (which I have already backed up, of course):

"Explosions on lower levels. Hmm. How's the controlled demolition "theory" for the destruction of the World Trade Center twin towers NOT possible?

Exactly what time was it when each of the planes hit? Seismic data vs. FAA-9/11 Commission.. Seismic wins. Then in 2005 NIST moves in to gum up the data, by adding 3 seconds to the time of Flight 175's hit at 9:02 and 54 seconds, instead of the Commission's 9:03 and 11 seconds or that of the live TV coverage... 9:02:59 ...which Pavel Hlava's time stamped footage nearly syncs up with...

For one, many tower collapse videos have no sound at all. Second, the cameras that were recording the collapse would likely not be able to handle sounds as loud as explosions and will either shut down the sound or blend it together into a continuous roar as heard on some of the videos that do have sound.

Here is the Nextel 2 hour Naudet program "9/11: CBS Special Inside WTC with Jules & Gideon Naudet" Leslie. I've watched it before several months ago, and I don't remember where or if there were explosions recorded, but the [High Explosive (HE) damage patterns IMHO] are quite revealing in both videos. I seem to recall that this special was NEVER broadcast "live" on US television for whatever reasons (from one of my many DVD's IIRC).

Make that first blast at 06:22 BTW.

"The eyewitness story, with extraordinary video that has never been broadcast, will be presented with no national or local commercials or promotional announcements. Public service messages, made possible by Nextel, will be incorporated into the broadcast. Robert De Niro will host the presentation. "We have believed from the outset that, out of respect for the important subject matter, this program should be presented with limited interruption and no traditional commercial or promotional content," said Leslie Moonves, President and Chief Executive Officer of CBS. "Nextel shares our sensitivity and wants to ensure that '9/11' simply documents what happened on that day."

It's hard to believe how much time has passed.

Five years ago this weekend, on March 10, 2002, CBS aired the documentary 9/11, hosted by Robert DeNiro. The two-hour prime-time special, chronicling one summer in the life of the Duane Street firehouse--whose firefighters were the first to arrive on the scene in response to the initial attack of September 11--was a national event. Forty million people watched the broadcast, which ran without commercial interruption. (Nextel supported the program with three public-service spots.) Sixth months later, on the first anniversary of the tragedy, 9/11 would air in 140 countries. ... "

I've been reading this article about what NIST states about wtc 7 on not hearing any "loud noises" to indicate that explosives were used.

Here is the quote:

Spurred by conspiracy theorists' questions, investigators did look specifically at the possibility that explosives were involved. "Hypothetical blast events did not play a role in the collapse of WTC 7," the report states, adding that investigators "found no evidence whose explanation required invocation of a blast event." Moreover, the smallest charge capable of initiating column failure "would have resulted in a sound level of 130 dB [decibels] to 140 dB at a distance of at least half a mile." Witnesses did not report hearing such a loud noise, nor is one audible on recordings of the collapse.
But when you listen to this recording...it clearly points out that this statement is false.



The question is, does anyone know where this sound came from and was it before or after Both World Trade Centers 1 and 2 came down?
