A Strange Sound Heard All Over The World Last A Few Days

I'm really don't believe this video because I did not hear it, but The most thing that get my attention is that all the internet talks about it and I've notice that this sound is heard in the countries which are near the earth pole.

This sound is really strange and terrifying. Some people write in their comments that sound are an alert to the end of the world and they believes that the world ends in 2012, others said that this sound is a fake. I don't really decide if it's a fake or real . I've checked out the YouTube and I've found a lot of videos talked about this. 

Please write down your a comment a bout your opinion and if you heard such like sound or not.
