I looked at your linked website, and the graphs. I don't understand them.What are the values, the measurements. I can't make them out, except for some sort of spike. I cannot tell the time frames or the causes...are these rems, gieger measurements, I don't understand what these graphs say, except some type of increase in something, of an undefined amount... Please explain...maybe it's air temperature... Unfortunately I can't explain much, I'm not a scientist. Dr Wood painstakingly compiled the data from those graphs from here: magnet.gi.alaska.edu/access_data_back.html

Wait a minute. Isn't there a whole other breed of wackadoo argument that gets all huffy because the holes weren't plane-shaped?

I was watching The History Channel yesterday, and they included an interview with at least one person who heard the second plane. This was preparatory to showing a picture the person had taken that also showed the first plane. Really, this is one of the stupidest arguments out there. It denies astonishing amounts of evidence. Did you get the name/address of the person's doctor? I'd like to see the reports on hearing-repair. Now wait a second here. Are you saying that a commercial jet flying low overhead will make you deaf? Drive on the 401 Hwy. near the Pearson International Airport outside Toronto sometime! They're flying overhead landing or taking off every few minutes... I mean, C'mon.

No one in New York reported the deafening sound of wide-body commercial airliners hitting the towers at full throttle. You know I find this really funny cayse I watched MSNBC yesterday cause they had "As it happened" on. After the first plane had hit and they were trying to figure out what had happened, they were talking to a caller who stated that she "Heard the roar of a jet engine and looked up to see a plane hit the WTC." At the time of the second plane hitting they were talking to a second woman who said something like, "Oh my god, a huge plane just flew over my building and hit as well." Yeah, no one reported that, except those that did live on TV. How loud is a "roar"? Did it cause her to faint?

From what I've been seeing on the web, the noise from a jet would be around 120 DB. Rock concerts are in that area, and sometimes even louder - and that is noise over a sustained period of time!

I'm sensing that no matter what data we show you, you will just ignore it (per usual). Geez, finding out the noise of a jet going overhead a few hundred feet at 500 mph isn't that hard to figure out is it?
Anyone here got a definitive result for this - so we can nip this in the bud?
And actually, the loudest db level I've come across so far is a Military jet aircraft take-off from aircraft carrier with afterburner at 50 ft . . . 130 dB.
EDIT: No, the loudest so far : An Apollo Launch - 188 DB !

I used to work on the glide slope electronics which are located only a few dozen feet from the runway. I was there, finished my work on several occasions, and having been informed by ground control that I would not be able to take my vehicle onto the runway to get back to the office for some time , I would sit outside and watch various aircraft , 727, 737, 747, L1011 take off. That's at considerably more throttle than landings.

Jet planes 10 times louder than rock concerts... www.newton.dep.anl.gov/askasci/phy99/phy99405.htmQuestion: We are a 5th grade class and we would like information about decibel levels. Do you have a list of decibel levels for common sounds? Such as voice, airplane, etc? ------------------------------------------------ Answer: First, remember that the decibel (dB) is a logarithmic unit, meaning that you cannot add and subtract dB like ordinary numbers. For example, an increase of 3 dB is a doubling of the "strength" of the sound, and an increase of 10 dB means that the sound is 10 times as loud; i.e., 70 dB is 10 times as loud as 60 dB. Now for the list: Threshold of hearing.....................0 dB Outdoors, no people or traffic..........20 dB Background noise in a library...........40 dB Ordinary speaking voice.................60 dB Heavy traffic...........................85 dB Power lawnmower up close................90 dB Motorcycle (rider)......................90 dB Chainsaw...............................100 dB Rock music at concert..................110 dB Jet plane takeoff at 100 yards.........120 dBThreshold of pain......................140 dB These noise levels are approximate, and depend on many factors. Noise levels of 85 dB and above are considered potentially damaging over time; for example, workers are not allowed to spend more than 30 minutes per day at 110 dB -- the level of a rock concert! gary e myers =========================================================
