Discussion Sky trumpets: what were they?

[nakolas]

The sky trumpet phenomenon (sometimes called sky noises or strange sounds in the sky) refers to a series of reports, especially in 2011–2012, where people around the world claimed to hear loud, trumpet-like, metallic, or rumbling sounds coming from the sky. These noises were often described as eerie, mechanical, or like the "blowing of a horn."

People compared it to a trumpet, shofar, or didgeridoo; others said it resembled industrial machinery, train horns, or metal scraping, lasting from a few seconds to several minutes. Widely reported in Canada, Ukraine, the U.S., Germany, Belarus, and other countries during 2011–2012.
Here's a video of what I'm talking about.

idk some Reddit scientist probably answered it in some thread somewhere.

Consult the graph:

I remember watching those videos as a kid and being freaked out

I never heard any IRL, atleast I don’t think

Wait hang on

Here are my theories:

• Moderate-sized meteors causing sonic booms as they strike the lower atmosphere.[8]
• Gas explosions, either by ignition or sudden release of trapped deposits:
  • Gas escaping from vents in the Earth's surface.[citation needed]
  • With lakes, bio gas from decaying vegetation trapped beneath the lake bottoms suddenly bursting forth. (Plausible, since Cayuga Lake and Seneca Lake are large, deep lakes with millennia of deep deposition of organically enriched sediment.)[citation needed]
  • Explosive release of less volatile gases generated as limestone decay in underwater caves.[citation needed]
  • Underwater caves collapsing, and either the released air and/or a wave of water pressure vacuum abruptly arriving at the lake surface.
  • Volcanic eruptions (in places near known volcanic activity).
• Military aircraft surreptitiously creating sonic booms (this origin does not explain these sounds being heard before the advent of supersonic flight, but this entry could be extended to include military cannon-fire practice).
• Earthquakes: Shallow earthquakes can generate sound waves with little ground vibration: The "booming" sound is heard only locally, near the epicenter.[8][9]
• Avalanches, either natural or human-caused (for avalanche control).
• Weather: Distant thunder, or loud sounds from wind damage.
• Atmospheric ducting of distant thunder or other loud sounds from far off.[note 1]
• Secondary atmospheric waves from plasma impacts of solar CMEs. CMEs generate plasma shock waves in space, similar to the sonic boom caused by aircraft flying faster than the speed of sound in Earth's atmosphere. The solar wind's equivalent of a sonic boom in the Solar System plasma medium can accelerate protons up to millions of miles per minute – as much as 40 percent of the speed of light.[11] This is a proven source of auroras, but has never yet been shown to be sufficiently forceful and sufficiently abrupt to cause a "boom".
• Possible resonance from solar and/or Earth magnetic activity inducing sounds.[12]
• Breaking waves: A line of breaking waves on a rocky shore is capable of producing booming noises at low frequencies, thereby allowing the sound to travel for longer distances.[13

Our sky is an illusion and the stuff that created it, is very huge - "biomechanical" - and occasionally very loud.

Ofc, it only seems loud to us because the sound is from a different dimension.
