New Alienentity video on WTC 7

[Grizzly Bear]

Other than you not having much familiarity with accoustics?
Seriously... you're comparing a sound barrier used on major traffic venues to the urban fabric of a major city... I'm not a genius when it comes to discussing acoustical behavior but there's a rather spectacular gap between the two...

Buildings. It's a direct shot from the camera to the building. While WTC7 has many standing in between.

What point are you trying to make?

Well if sound were to so easily reverberate in NY wouldn't it make any noise unbearable? That effect would apply for everyday, not just 911. Right?

I think you're just grabbing on to a phenomenon that does happen and applying it here to justify your cause without really thinking about the implications.

That the OP should take into consideration that one scenario has obstructions and the other does not.

Did you notice how your video is so much louder than Alienentity's?

The collapse of the building on your video is clearly heard. Making the other sound like a whisper in comparison.

What would you attribute that to?

Tall buildings aren't quite like highway sound barriers that are specifically engineered to reduce noise levels. Acoustical response doesn't necessarily apply the same in all situations. The point you missed or apparently don't understand. Some materials reflect sound, and others absorb it, buildings aren't monotonous. Consider it next time you ask.

As for your quibble about obstruction, masking the sound; doesn't make a significant difference if it were amplified or not, a series of explosives detonating at 140 decibels doesn't go unnoticed from that distance.

No.

True, but you portray it as if some amplification was bound to take place. More so you try to make us believe that on 911 this would have happened. Building structure and layout would have contributed to "amplification". But on any other average NY day it wouldn't.

In other words while the phenomenon(reverberation) you mention does happen and I agree it happens. It's a long shot to say it happened in that particular place at that particular time. More so given that your thesis proposes there was no explosion. So there isn't even a test to determine that it would have sounded like you claim it would. What we do get in your video is a very faint sound level of the collapsing building (faint compared to other videos brought forth). So based on your reverberation theory the sound of the collapsing building should have been much much louder, but it was not.

 

[Java Man]

No.

You should go back and listen to both then.

 

[TJM]

Don't have to. I understand the difference.

 

[alienentity]

I actually increased the audio by 10db. Didn't see the point in going higher, since you can always crank the volume on your speakers.

I take your point about the lack of other buildings, but as you may have noticed in dense urban areas, sounds do actually travel quite efficiently because the surfaces don't absorb much energy.

However, assuming that sound does attenuate in either case, there's no physical reason why it would attenuate so much that you couldn't hear a very loud explosion. I won't get into the technical details, but we've discussed them thoroughly before.

I'll give you another example, which is the famous Ashleigh Banfield video, where she's interviewing a lady a few blocks from 7 as it comes down.
You can hear the building collapsing (kind of a vague rumble) but absolutely NO explosions of any kind at that time.

So the question becomes, why did the mic pick up the rumble, but not the 'explosion' which truthers seem to think must've been there?
Answer: there was no explosion. The mic doesn't differentiate, it just picks up any sounds that are there.

Hope that helps.

The bold part is correct. NYC is loud by some standards. It's safe to say that the loudest source of every-day noise -- rush hour traffic -- would be much more tolerable if the major roads ran through forests of trees instead of valleys of concrete.

("reverberation" isn't the word you were looking for. Reflection is better. I don't know of a good word for non-attenuation.)

Don't even bother with the high sound barrier walls. They baffle sound outside the immediate highway corridor, but travelling between them, it is like tap-dancing inside a huge guitar body.

They recently installed sound walls along the on-ramps to IO-5 in Tacoma. Driving through there at night with no other traffic, the sound of my own tires is astoundingly loud. The walls are there to keep sound IN.

The canyons of the city do the same thing. Listen to the backgrouind noises on any video from that day. Notice on the Naudet film that the sound of the first palne in-bound does not seem to be at the same volumn all the way. This is because it passed behind a few buildings and out of line of sight.

In the some of the shots of the second plane, it cannot be heard until right overhead, but on the Hezarkhani video, it can be heard some distance out.

Tall buildings baffle the sounds of aircraft until they are right overhead.

But a noise originating inside the canyon walls will stay inside and travel some distance. Note that we can clearly hear the much softer sounds of the breakup of WTC 7 much more clearly as more of the action occurs at street level, well into collapse.

So, basicly, Java Man, you have nothing of forensic value here.

I created a proper mono track. The original was panned hard to one channel.
I also brought the audio level up by 10 db or so. STill doesn't sound like an explosion tho

When you watch the Penthouse collapse into the building so neatly it is no problem to tell that this was a deliberate act to drop first one Penthouse inside the building and then the other.And finally to cover them both with the wreckage of the main demolition.

There was something they wanted to fide in the Penthouses, no error..

They still had Freon in their HVAC system and were going to use it to generate a cloud of phosgene gas and kill everyone in the area, maybe. But they might have decided that would be too big a giveaway.

I was there, those sounds almost made your body rumble. It was something you never forget. This is why I want the CT's to give me more than just a few people saying they heard explosions but hundreds, **** thousands who were there.

Or at least one video where "BOOM BOOM BOOM BOOM BOOM, (collapse initiation), BOOM BOOM (Building Fall)" is heard.

Stop adjusting the volume on your computer. That should help.

That's the first precaution I took, not to alter volume levels.
