Strange low-pitched rumblings, anyone?

[AlienGirl]

Over the past couple of weeks the roomies and I have been hearing strange, very low-pitched rumbling/booming noises. We're too far away from the bombing range for it to be bombs; a few times it almost sounded seismic.

We live in Bellevue, WA, near Seattle.

Has anyone else been hearing weird low sounds? Anyone have an idea what the heck they are?

3. 2 Others Reported The Same Thing

In British Columbia and Minnesota.

4. anywhere near Boeing plant?

Could be jet engine testing.
Sometimes I can hear it from Pensacola Naval Air Station 45 miles away.

7. sometimes we hear deep low engine noises from Miramar

sounds like they are doing some testing. It is almost just a low vibration, not really a loud noise.

8. We're all familiar with jets

This sounds like either it's jets going ultrasonic, or bombs! Those of us who are familiar with Space Shuttle sounds think it sounds kind of like a shuttle taking off or landing.

11. Jets in test stands

don't sound like jets flying over.
The stands have noise reducing baffles and the sound is more of a low rumble.

20. Interesting

I was perplexed to see 3 F-18's fly overhead (at a slow (for them) speed) the other day headed out to sea. I'm in Oregon, and the ANG doesn't fly Navy jets to my knowledge. I wondered what was going on.

(Yes, I can tell by them apart from F-15's and 16's. The tails were clearly visible.)

5. did you ever notice

if one of your roommates happens to be in the bathroom whenever this happens? ;-)

12. Despite Jag's reputation for noisy emissions...

these were desinitely coming from *outside.*

6. I've heard it too

HAARP

Haarp, Chemtrails and the New War Technologies
http://www.coastalpost.com/03/03/12.htm

Try these for starters.

9. Look here:

http://earthquake.usgs.gov/recenteqs/

There are sonic booms, distant thunderstorms, rockblasting and mining operations, and all sorts of other things that go bump in the night.

10. You may be hearing resonances

(identified thread)

By an interesting synchronistic event, I just put this explanation into a completely different thread (http://www.democraticunderground.com/discuss/duboard.php?az=show_topic&forum=105&topic_id=183624).

Stand near the wall of a building made with corrugated walls and clap your hands. You will hear a ping. That's a new waveform caused by the building shaping the old one.

The mountains can form amplifiers and other acoustic abnormalities that modify sound.

There are forest fires in Alberta and British colombia. You may be hearing wierdly distorted aircraft and helicopter noises.

13. Distant thunder?

Here in the Sacramento Valley in Northern California two weeks ago we had a spectacular whole nightof thunder and lightning with a little rain. Weather report said ~5,000 lightning strikes! Since then we've had some dry lightning/thunder pass through. WEIRD weather for this area. Maybe Seattle has had some of this, too?

14. Do you live near a zoo?

Maybe it's a bull elephant in musth... :shrug:

15. More than thirty years ago,

I could hear the early morning prop airplanes warming up at National Airport in Washington DC if weather conditions were right. That was at a distance of about 4 miles, and it was a low, kind of rumbling sound. i knew what it was because I worked at the airport, and if I worked early morning shift I'd arrive at the right time to see the planes at the other end of the runway, the engine sounds baffled by the hangars and a fence at that end of the field, sending the sound several miles down the Pototmac River.

Sometimes sound travels in odd ways.

16. Hey Tucker

We posted on the same subject.

I have been trying to think of an explanation I heard of long ago

of mystery low pitched noises. I finally found it!

Google (Barisal Guns).. Good stories!

17. Read this website and see what you think...

Aurora
<http://members.macconnect.com/users/q/quellish/Aurora/Aurora.html>

The background pic on this website is notable because it is the contrail of what is believed to be "Aurora" a hypersonic aircraft. The sound of this aircraft in flight has been described as a rumble, not the steady sound one would expect to hear from high performance jet aircraft.

A couple of excerpts from the site which I found to be very interesting:

"During October of 1985 the USAF ASC launched the Advanced Aersopace Vehicle program to develop advanced hypersonic military aircraft. In December of 1985 the National Aersopace Plane program was born, a civilian led (though the majority of it was funded through DOD agencies) national effort to develop a single stage to orbit vehicle."

"The AURORA name itself is quite significant. As noted above, Aurora had a place in Greco-Roman mythology. She was the goddess of the dawn (also known as Eos) who created the stars and set them out at night. Lockheed programs, recon systems in particular, have had a long history of being named after astrological figures and constellations. The original name for the A-12 was Cygnus, the SR-71 Oxcart (the European name for the Big Dipper), the U-2 carried the name Isis. So the Aurora name suggests a Lockheed recon program. The fact that it is a single word codename is also worthy of note. Single word indicate a much higher level of classification that other programs- more secret than even SENIOR TREND, the F-117A program."

18. Specific information on the "rumbling" sound...

Aurora Rumblings?
<http://www.f4aviation.co.uk/Oldstuff/aurora/aurora.htm>

This was written about an experience of an individual in England during the Balkans Campaign:

"The silence was broken by a low rumbling that initially did not draw my attention, but due to the rapid increase in volume I looked up, scanning the clear skies for a possible visual contact with a navigation light. Although I scanned this way and that, I could not not see any movement, and by this time I judged the sound to be directly overhead, rapidly moving away from me. This is when I noticed a distinct change in the sound as it went from a loud roar to a definite intermittent pulsing rumble. I remember reading a report that Aurora engine noise sounds a bit like a train, the rapid throbbing pulsing sound being very similar. It continued for a short while until silence once again returned to the still night. I estimated that the whole over-flight lasted only one minute, on a south to north heading. It gave me the impression that it was travelling at high speed and high altitude, due to the other experiences I have had observing aircraft."

19. Trains?

If the wind is blowing right, I often hear/feel the train 6 miles away. Sometimes they stop on a siding to allow other trains to pass, when they get rolling again they rumble.
