Since lots of other people would have heard it, I guess "strange" is relative.
Need to know if anyone else heard the incredibly strange sound last night at approximately 1:15am. I live near the corner of Walgrove and Palms, and the noise, whatever it was, woke both my wife and myself up. Definitely sounded like it was a "sky-based" sound rather than a "land-based" sound. For crying out loud this sounds stupid. I'd say it lasted a good 20-30 seconds. Was extremely loud. Sounded like a series of loud sound waves (that's the best way I can describe it — didn't sound like anything I had ever heard before outside perhaps a sci-fi movie). Was definitely NOT a helicopter because as a ten year Venice resident, I have heard plenty of those. Very well could have been someone parked outside playing extremely loud music, but I have never heard music that loud, and have never heard music that strange (and I have heard more than my fair share of strange music). Perhaps it was a firework somebody launched that was a misfire and it ended up stuck in a tree? I have no idea. Have yet to canvass my neighbors yet, but I will do so shortly. And no, I was not on any drugs.

…STRANGE SOUNDS BEING REPORTED ACROSS THE FLORIDA BIG BEND…
THERE HAVE BEEN SEVERAL REPORTS OF VERY STRANGE SOUNDS FROM THE WOODVILLE AREA SINCE ABOUT 645 PM EST. THE NATIONAL WEATHER SERVICE BELIEVES THIS PHENOMENON IS BEING CAUSED BY THUNDER FROM DISTANT LIGHTNING STROKES… BOUNCING OFF A VERY STABLE LAYER ABOVE THE GROUND. THIS IS CALLED DUCTING…AND CAN ALLOW SOUND TO TRAVEL UNUSUALLY LONG DISTANCES. THIS SOUND HAS BEEN MISTAKENLY ATTRIBUTED TO POSSIBLE TORNADOES…BUT WE AT THE NATIONAL WEATHER SERVICE WANT TO BE VERY CLEAR THAT THERE ARE NO TORNADOES … AND NONE ARE EXPECTED.“
My sentiments as well. When the strange noise videos began getting popular, the Fundies were claiming that it's trumpets from Revelations.PCWilliams said:I think some people are hearing something but, overall, i'm suspicious of many of the more recent claims coming forward. With 12/21/2012 nearing, many people will either have fun hoaxing or trying to cash in on the coming doomsday.
Interesting official explanation:
After a sound has traveled along a duct like this, I'd imagine it would get quite distorted, unrecognizable, but still loud. [/FONT][/COLOR]
That sounds very reasonable. I was a Sonar Tech in the Navy and the sonar set I worked with was a Surface Duct Sonar. Basically the surface duct is the part of the ocean that is a fairly constant temperature from the surface to a certain depth. At that depth, the temp falls off quickly. The depth of that duct determined the range of our active sonar. Simply put, the sound waves are transmitted and reflect off of the barrier created by the sharp temperature decrease back to the surface. Then reflect off the surface. The deeper this duct was, the greater our range. Here is a link that shows how this works:
Wow. I haven't thought about this in years.
Sophistication of the technology
Establishing the viability of this new technology, NASA's solar-powered aircraft Pathfinder, with a 100-foot wingspan, reached an altitude of 71,500 feet altitude in 1997, and its fourth-generation successor the "Helios" flew at 97,000 feet with a 247-foot wingspan in 2001, two miles higher than any previous aircraft.
For the next tier above the Earth, in the upper stratosphere, DARPA and the Air Force are collaborating in the development of the Falcon Hypersonic Cruise Vehicle. Flying at an altitude of 20 miles, it is expected to "deliver 12,000 pounds of payload at a distance of 9,000 nautical miles from the continental United States in less than two hours".
Although the first test launches in April 2010 and August 2011 crashed midflight, they did reach an amazing 13,000 miles per hour, 22 times the speed of sound and sent back "unique data" that should help resolve remaining aerodynamic problems.
Any noise from Falcon would be heard over a much wider area. I doubt it would make any though, it's basically just a rocket.
Unless you mean something to do with audio ducting? But I can't see any connection there. What were you thinking?
I just heard in the south of spain 4 am what can only be descibed as a jet which at first at thought it was but i looked and couldnt see any aircraft above and the noise came from the sky as if it would be flying evrywhere at once it was more like thunder but jet sounding if that makes sense it was very strange and freaked me out it seemed to dissapear as if it was mvoin away but like i say am pretty sure it was no jet unless the sound of a jet from far away that travelled but i doubt it it was like it was litterarlly over my head at one point , i have seen the you tube videos of the booms ect it didnt sound like them but i am aware peple are reporting strange things and now have heard my self am just looking for answers like eveyone else i suppose
We had a fairly strong inversion Thursday morning with a shallow layer of cool stable air at the surface and NE winds advecting a layer of relatively warm moist air in off the ocean. It took until about 9AM for sun to heat the surface layer enough to mix out the inversion. I could here traffic from a distant highway, traffic that I only hear if their is thermal cap and general wind flow out of the east.
Now what is described above is what often happens here when we get big but slow moving diurnal storms. They'll tap cold air aloft which gets driven down to the surface in strong down drafts. But the storms are mostly stationary; generally forming and dieing in place as the CAPE (convective available potential energy) is used up with storm propagation occurring along outflow boundaries (downdrafts hit the ground and spread laterally). As a storm collapses the atmosphere becomes hyper stable. With the surface temp having dropped from say 92F to 70F. You'll often end up with stratiform rain from mid level clouds where the original storm occurred and new thunderstorms radiating out away from that origin but connected to one another by the stratiform deck. The most spectacular thunder I've heard was when storms over ten miles apart both dropped CG lightening and then CC lightening spanning the entire distance between them. The thunder created by such an arc is continuous for 30 or more seconds because the CC lightning stroke was over 10 miles long and the sound is trapped below the inversion so you end up hearing the distant thunder at a much greater volume that usual. Some kind of constructive interference occurs because this kind of thunder really lasts and isn't cracking but is very intense low frequency the rattles everything in the house.
In brief, if I'm not cracked on this. Thunderstorm ends up stabilizing the atmosphere by convecting warm air up and cooling the surface. CAPE runs out. Storm collapses and spreads out into a mid-level stratus deck producing light to moderate steady rain (most weather radars paint the signal yellow at this intensity). However, thunderstorms may be actively forming along the outflow boundary radiating away from the original storm. Inter-cloud lightening then travels a great distance through the stratus deck between discrete cells.
There's got to be a real scientific write up about this as opposed to my hypothesizing.
i agree, see my post below today 17.11.13. I live near Valencia . The only thing I don't agree with in your analysis, is that it sounds like thunder. i just hear a constant sound , relentlessly consistent, but does vary somewhat in strength, which makes me think it could be wind or atmospheric pressure related....
These sounds do occur and are very real, not to mention annoying. i am in the south of Spain, near Valencia. I am hearing them right now. It lasts for about 3 hours and i hear them approximately at monthly intervals more recently, and never heard them before, although i have only lived in this location for two years.
The noise is simple to describe but my phone does not record it well, The level of the "loudness" is drowned out somewhat when society wakes.
The sound occurs at what would appear to be a regular time ( which in itself is odd) or it is that with all the normal noises of a town it is drowned out. But seems tobe very audible between 05:00 -09:00.
Dogs seems to react to it also.
So the sound sounds like a solar wind might , a wind, constant it does not really vary. It seems to come from the sky.
The best way to describe it, is like a jet has flown over and you are hearing the "after jet noise" but for hours. Another similar sound is when you live next to a motorway/freeway and you can hear the road traffic noise .
it is loud enough to penetrate double glazing.
I live very close to the sea and there are mountains nearby. the sound is not being generated by any machine or human, it is way too vast, constant and consistent.
THOSE ARE THE FACTS
