Witnesses say the volume ranges from mild to deafening and describe the sound variously as a metallic-type groaning, a cacophony of orchestra instruments, loud humming, and the blare of a thousand trumpets.
The latest recorded case occurred on April 4, 2015, in Germany. In the video below, to which I’ve added edited segments with increased volume for clarity, we watch as a couple rush to swing open a window to record the unusual noise. A woman asks in German, “What is that?” while a child stands motionless, stunned, in the street below.
Scientists have found no explanation for the sounds and have variously proposed earthquakes, methane explosions, supersonic meteors, electrical power lines, and shifting sand dunes as potential explanations. One person shared his suspicion on a popular forum:
“I think people are so accustomed to hearing these sounds in their back yards (I hear them in mine) they don’t realize that this is not normal, it is the hidden machines being used to control the weather and sometimes to cause quakes. They are weapons hidden among us.”
Others believe the unexplained sounds could be the slippage of the earth’s core, HAARP, extraterrestrial probes and measurements of the planet, and God’s trumpets.
The mysterious sounds have been heard and recorded in areas all around the world including the USA, England, all throughout Europe, Canada, New Zealand, and Australia. The phenomena seem to have begun in earnest around the second half of 2011.
