With frequent observations of these sounds, I noticed that this mysterious sound can be heard before or after the bigger earthquake in the world. It probably has a connection from the shifting of the lithospheric plates. What do you think about it?
The mysterious sound is probably related to the earthquake in the world.
These may be associated with atmospheric changes or low frequency acoustic emissions in the range of 20 and 100 Hz, modulated by ultra-low infrared waves of 0.1-15 Hz.
The causes of their occurrence are different: earthquakes, volcanic eruptions, hurricanes, storms, artificial interventions into the atmosphere or the earth’s mantle …
The sound in the video where the person is pointing the camera down into the grass is from a cricket; it is a species that produces an incredibly loud noise, we have some where we live. A couple of the other sounds I believe are fakes, in the third one, with the wavy clouds, I recognize sounds from the movie Red State, from which the trumpet sound has been used for fake “trumpet in the sky” videos. So, I have problems trusting the other sounds being genuine. The phenomenon is real, but unfortunately there are a lot of people putting out fake videos.
Could be related to haarp.
