Mysterious sounds coming from the sky

[Hum]

Mysterious sounds have been heard booming from the sky all around the world ? in some cases they were so loud they set off car alarms.

The unsettling noises were heard recently from Europe to Canada, sounding like groans and powerful horns.

In Germany noises coming from the sky were recorded on a video camera and uploaded to YouTube, with car alarms clearly heard going off in the background.

The internet has been buzzing with theories about what the sounds could be, with suggestions such as Jesus returning :huh: and the world ending put forward.

But experts have said that there are rational explanations.

University of Saskatchewan physics professor Jean-Pierre St. Maurice told CTV that it?s electromagnetic noise emitted from auroras and radiation belts.

Geoscientist David Deming from the University of Oklahoma, meanwhile, has previously written about a phenomenon called The Hum :shifty: ? ?a mysterious and untraceable sound that is heard in certain locations around the world by two to ten per cent of the population?.

Writing in the Journal of Scientific Exploration, he said that sources of The Hum could include telephone transmissions and ?aircraft operated by the U.S Navy for the purpose of submarine communications?.

According to Nasa, the Earth has ?natural radio emissions?.

The Agency said: ?If humans had radio antennas instead of ears, we would hear a remarkable symphony of strange noises coming from our own planet. Scientists call them "tweeks," "whistlers" and "sferics."

'They sound like background music from a flamboyant science fiction film, but this is not science fiction. Earth's natural radio emissions are real and, although we're mostly unaware of them, they are around us all the time.?

For instance lightning can produce eerie-sounding radio emissions, Nasa added.

Earthquakes can also produce sub-audible sounds, according to seismologist Brian W Stump from the Southern Methodist University in Dallas.

Sonic booms from military aircraft, maybe?

It's Jesus and his big boom box! When he comes down, we shall hear in all it's glory, " It's Raining Men!"

I posted a few weeks ago that I heard some very loud roars for a couple of minute and thought they were some military plane miles up in the sky as that was all I could see both times I heard it, but the plane was far too high and the noise was vibrating in the house through double glazing windows

One of those videos sounded like the tripods from War of the Worlds :D (EDIT - didn't refresh in time)

go to Alaska in mid winter when a solar flare hits, you will hear "The Hum" its like static a lot of the time

Sonic booms from military aircraft, maybe?

these are nothing like sonic booms, its like you turn a radio to a static channel low, then slowly turn it all the way up then it fades out

Loud noises where I live is nothing unusual. Helicopters and artillery training at the military base about 3 miles from me is a 24/7 operation.

Not going to lie if I heard that live it would scare me. about a decade ago I can remember hearing a VERY loud almost hissing noise from seemingly nowhere that scared me and everyone near where I lived. and they never could find the source of the noise.

Military testing out 'sonic cannons'. :shiftyninja:

You know what...outside earlier I heard a very loud, odd electrical sound just seemingly coming from nowhere - almost like i was right next to an electricity power distribution centre. I kept thinking "what the hell is that" as there were no such sources of the sound nearby!!

It was the trumpet of God, annoucing the end of times with some smooth jazz and blues :cool:

[Ntrstd]

Some causes are ship's foghorn, sports horn or trumpet that spectators use, electrical generators or substations, sonic boom from aircraft, aircraft landing or taking off, earthquake, building construction, mining operations, music concert, rain or wind or thunderstorms, military excercises, someone leaving their radio or TV turned on and making static.

Some of these sounds can carry for kilometres because of wind or unusual air effects.

It was the trumpet of God, annoucing the end of times with some smooth jazz and blues REM, 'It's The End Of The World As We Know It'. :cool:
