Strange sounds heard worldwide!?

[Eddie]

There is a possibility that the video embedded above is a viral marketing video for the Cloverfield movie sequel. However, sounds of this type do exist and have been observed lately. My wife was disturbed in the middle of the night Monday night by such sounds; she asked me what they were but I couldn't say. My guess is that some phenomenon is causing molecules in the upper atmosphere to oscillate at the right speeds to produce such sounds. Might be HAARP, fluctuations in our magnetic field, or some interaction between the two.
