Renowned Geophysicist Says Strange Sky Sounds Are Real

Dr. Elchin Khalilov, a geophysicist and a professor in Azerbaijan, has been conducting research into the recent wave of strange sky sounds.

Dr. Khalilov refers to the phenomena as “sky hum.” As a geophysicist, he has become intrigued by the numerous reports and recording of the sky sounds. While others in the research community might be inclined to dismiss the whole thing as nonsense, Dr. Khalilov has been working with other researchers to explain what might be causing it.

“We have analyzed records of these sounds and found that most of their spectrum lies within the infrasound range, i.e. is not audible to humans. What people hear is only a small fraction of the actual power of these sounds. They are low-frequency acoustic emissions in the range between 20 and 100 Hz modulated by ultra-low infrasonic waves from 0.1 to 15 Hz. In geophysics, they are called acoustic-gravity waves; they are formed in the upper atmosphere, at the atmosphere-ionosphere boundary in particular. There can be quite a lot of causes why those waves are generated: earthquakes, volcanic eruptions, hurricanes, storms, tsunamis, etc. However, the scale of the observed humming sound in terms of both the area covered and its power far exceeds those that can be generated by the above-mentioned phenomena.”
