Not a sustained noise I take it? The other videos last several minutes, did the sounds end abruptly as you recorded them?

Have you definitely ruled out jets, trains, trucks, large engines, construction equipment, etc?

The skepticism shouldn't klick in about someones claim in hearing an odd noise.
it kicks in when people start answering based on...nothing in particular (angle trumpets ushering in the apocalypse, alien crafts, mole people, etc).

The discussion, to my knowledge, is typically about what it could be...from magnetic and solar storms creating odd but not unnatural frequencies in the atmosphere to etc.

Like a UFO...sure, they exist..but now lets try to figure out what they are. ok, that is a weather balloon, that is a satellite, etc...to be skeptical about the existance of UFOs is being a bit of a dimwit.

Try to see if this noise happens often and you simply haven't paid much mind to it until now (now that your alerted to it..before, it might have simply been one of the multitudes of background white noise we tune out daily) If it happens often, try to find patterns, move to different locations, try to zero in on where it is coming from if its possible...or if its just all around no matter where you go.

The noise in this video, I have heard before. The whale song noise in some of the videos or the mechanical ones, I haven't heard myself.

I will keep my cell charged and with me to try and get the sound.

Yep, same noise i heard in Australia, except my experience lasted 20 minutes.

I heard the car go by then some wind blowing on the mic....really

My husband and I heard this about a month ago in San Francisco... We live very close to the ocean, and I initially though that it was the sea being very very loud, but I've never heard it so loud before, and it wasn't especially windy out. After about 30 minutes it just kind of stopped.

I have heard the sound twice now.

Has anyone noticed a change in their sleeping patterns after being subjected to the sound?

Never heard anything similar you guys are posting in NZ yet. I do hear a lot of sounds but we live only couple hundred meters from a freeway.

There are times I'd hear something similar then cut off then immediately start again, apparently, a big rig shifting to another gear! Some of the noisy bikes from a far sounded similar too.

To be honest I can't hear it. If you mean the road noises, then yes

I heard them myself. I heard the sound in the origian video and it is like mechanical wind and a freght train that never passes.

Edit: My dyslexia kicked in.

it truely sounds like your standing next to a stationairy (but running) truck.

i've seen/heard more convincing videos.

personally i have a hard time hearing it in your vid.

Yes, it was faint on my camera. At 15 seconds you can hear the pulsing hum. It did it continuously fro the entire time I was on break.

As I said, I was on a moke break at work. Rouglhy 5 minutes. It was happening when I went out so I grabbed my phone and recorded. when I went back in after my break, I watched the video (roughly 1 minute of the 5 minute break) and I could only hear the wind. So I quickly ran back out and stood in that doorway to block out the wind. Obviously a car drove by in the beginning, but the noise at 15 seconds is the noise I was trying to record. Some of the pulse were loder, some were softer.

It wasnt like the noie was right ontop of me and loud, if I had to guess, Id say it was a few miles away, but deffinetly coming from they sky to my right.

This video want to prove or disprove, it was just posted to say I heard it in Masachusetts if anyone is traking it.
