#52SDR (software-defined radio) enthusiasts also found something they can't identify: whistlers. You can see/hear them in this video: http://www.youtube.com/watch?v=0Hv--BR0ddE also briefly addressed here: http://www.youtube.com/watch?v=ZuRcaxpbYCw edit: not on topic, should have refrained from posting as it's a VLF radio phenomenon and not a sound.
There really should be a warning at the start of those videos telling you to turn the volume down.

#53Earlier quoted context omitted.
The sample is at 16x the original speed. And was heard over 5000km. In other words, not a bubble. Or if it was, it was a bubble worthy of its own wiki page.
Yeah, ok. It could have been wonderful, tremendous things. IE, lochy. But I've seen this on front pages at least 50 times and there has not been the tiniest insight into what that is beyond nothing at all. Occam's razor: It was a bubble, an electrical malfunction, a manufactured hoax, etc. Why don't you post a shaky video of bigfoot instead? At least the imagination has something to chew on there.
Occam's Razor isn't "jump to simple conclusions" or "don't bother thinking about it".
It's a rule of thumb stating that you should pick the simplest of two equivalent explanations. In this case there aren't even any proposed explanations, so it does not even apply.

#54I lived in Taos, NM for about a year and never heard the eponymous Hum. Recalling the recent Hacker News item about anechoic chambers, it wouldn't surprise me if it has something to do with how quiet the place is. On more than one occasion standing outside the house on the mesa outside of town, the utter silence of the place got to me enough that I had to go back inside and talk to somebody. Perhaps my mind would hav…
Maybe
Or it is there (and maybe everywhere) but we can't hear it
One thing that's noticeable when it's really quiet (and having lived in a place where it is silent at night) is that the threshold of hearing changes a lot. Something that's barely audible in normal conditions can "scream" at night
Example: the sound of soda fizzing in your mouth.
Re: List of Unexplained Sounds
#55"The Hum" [1] is the most interesting to me, because my dad claims he used to hear the exact same kind of sound -- like a diesel engine starting up -- in the mornings when he lived in an older house with my mother. [1]: http://en.wikipedia.org/wiki/The_Hum
I'm German currently in Canada and I heard the Hum apparently quite often in the last few days, never in Germany though. I've been on a very remote ranch somewhere 3 hours from Kamloops, BC and at first, I thought it was indeed a diesel engine starting up. Thing is, there was no neighbor close to that huge property. Then I heard it also 500m further away, same noise, same volume and also the same pattern. It's just f…
Well, but isn't starting a diesel engine something to be expected in rural Canada?
I mean, generators, trucks, etc?
Now see, in distances, it appears that lower frequency sound waves travel better. For example, take someone that's hearing music far away from you, the higher frequencies sound distinctively dampened.
So I wouldn't be surprised if a diesel engine could be heard a very long distance away in a quiet region
Re: List of Unexplained Sounds
#56I don't understand this. What, is there an archive out there that has every recorded sound by every single human being and along with has complete information about the recording, and only these 7 clips are not understood?
Partly - the specific ones all seem NOAA originated, which iirr is the American oceanographer group. They along with Navy proper have very vested interests in identifing unusual ocean sounds. But just as you can find parrots that say good morning, given enough fish swimming past enough deep seamicrophones, eventually one ofthem will sound like they are whistling a braoadway tune sorry folks, fun, creepy but in the en…
"Skeptical thinking" at its best
I'm really hoping you are a troll, because otherwise you're in "youtube commenter" category of intelligence
"eventually one ofthem will sound like they are whistling a braoadway tune""
Yes, please explain how a school of fish can create a sound with that power and spectrum, because you obviously know so much about mathematical wave properties and the laws of conservation of energy.
"NOAA originated, which iirr is the American oceanographer group""
Yes, and NASA works with planes and stuff

#57SDR (software-defined radio) enthusiasts also found something they can't identify: whistlers.

Actually, I work in a lab where I'm investigating ELF 'whistlers' that we've detected. It's really interesting stuff - we're not sure what causes them, but we've found some correlation between events and certain limits on the solar elevation angle. We think it might be ions getting trapped and moving along a field line.
Reading back my post I seem to imply that SDR enthusiasts discovered it, that wasn't my intention. This phenomenon was probably well documented before SDR.
When I first saw it, my first thought was "what a strange technique to run a radar, I wonder what the benefit is."
In ELF, would it be possible to set up three omnidirectional antennas and triangulate the source to get an idea in what layer of the atmosphere it's generated? I'd also love to read peer-reviewed publications, please post some references if you can.

#58This may be a bit off topic, but when I get into looking at this type of (mysterious, interesting) of Wikipedia article, I usually end up back at my favorite of the category: http://en.wikipedia.org/wiki/Wow!_signal
Best quote ever: 'In his most recent writings, Ehman resists "drawing vast conclusions from half-vast data"'.
"Also, the 1420 MHz signal is problematic in itself in that it is "protected spectrum": it is bandwidth in which terrestrial transmitters are forbidden to transmit due to it being reserved for astronomical purposes."
Wait... what?? If this has been enforced on Earth, then clearly other civilizations might make the same choice and not broadcast anything on that frequency.
Does anyone know if we are broadcasting anything into space on this frequency?

#59It's never aliens. It always turns out to be a prank, or ice cracking, or some other boring natural cause. Why can't it be aliens!?
nah, pretty sure it's aliens
