The Hum

 

The Hum is the name given to a series of phenomena involving a persistent and invasive low-frequency humming noise not audible to all people. Hums have been reported in various geographical locations.

The Hum is most often described as sounding somewhat like a distant idling diesel engine. Typically, the Hum is difficult to detect with microphones, and its source and nature are hard to localize.

 

Mistpouffers – the Unexplained Sonic Booms

 

Mistpouffers are unexplained reports that sound like a cannon or a sonic boom. They have been heard in many waterfront communities around the world such as the banks of the river Ganges in India, the East Coast and inland Finger Lakes of the United States, as well as areas of the North Sea, Japan and Italy and sometimes away from water.

Occasionally, these booms cause shock waves that rattle plates.

One explanation for why they are usually heard near water, is that inland communities are often too noisy to hear these booms.

Their origin has yet to be identified although they were sometimes blamed on meteorite impacts, gas escaping from vents in the Earth’s surface, underwater caves collapsing, or the air rapidly rising to the surface.

 

The Seven Trumpets of Apocalypse

 

At the beginning of  2012, bizarre sounds could be heard in locations all over the world. More and more recordings of these loud sounds that seem to come from the skies and have been so powerful that they rattled the walls and windows of buildings were posted .

At times they seemed to sound like multitudes of planes flying overhead and at others they sounded like apocalyptic deep horns. No one seems to have absolutely any explanation for this bizarre phenomenon yet.
