For several years now people from different countries have reported hearing strange sounds from the sky. Now scientists propose that what people are hearing is only a small fraction of the actual power of these sounds!
What are these sounds? What is causing them? Are they in any way related to our Sun and the biggest solar flares, do they come from Earth's inner core, or can they be attributed to an unknown astronomical phenomenon? Are they in any way dangerous to our planet? These specific very low-pitched sounds have been heard all over the globe, all the way from US, UK, Costa Rica, Russia, Czech Republic, Australia and other countries. According to Dr. Prof. Elchin Khalilov there can be a number of reasons why we hear the sounds. For example, such sounds can be triggered by earthquakes, volcanic eruptions, hurricanes, storms and tsunamis. Dr. Prof. Khalilov, a geophysicist specializing in the area of geodynamics and geotectonics, has analyzed these odd sounds and says that most of their spectrum lies within the infrasound range, which means there is a lot we cannot hear. 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. The problem is that people have heard this noise from the sky in regions where there was no geological activity, and the sound, in terms of both the area covered and its power, far exceeds those that can be generated by the above-mentioned phenomena. Is the Sun responsible? According to Dr. Khalilov "the source of such powerful and immense manifestation of acoustic-gravity waves must be very large-scale energy processes. These processes include powerful solar flares and huge energy flows generated by them, rushing towards Earth's surface and destabilizing the magnetosphere, ionosphere and upper atmosphere. Thus, the effects of powerful solar flares, the impact of shock waves in the solar wind, streams of corpuscles and bursts of electromagnetic radiation are the main causes of generation of acoustic-gravitation waves following increased solar activity." Recently we experienced the strongest solar radiation storm since 2005 and it is estimated that Solar Cycle 24 will peak in 2013. Sun cycles are natural and happen every 11 years or so. Geophysicists believe that these sounds coming from the sky could possibly be somehow related to increased solar activity. |
Does the sound originate from within the Earth's core?
Dr. Khalilov mentions also that the sounds could come from our own planet's core. According to Dr. Khalikov " there is one more possible cause of these sounds and it may lie at the Earth's core. The fact is that the acceleration of the drift of the Earth's north magnetic pole, which increased more than fivefold between 1998 and 2003 and is at the same level today, points to intensification of energy processes in the Earth's core, since it is processes in the inner and outer core that form the Earth's geomagnetic field." Back in November 2011, all Atropatena stations, a global network for the forecasting of earthquakes and record three-dimensional variations of the Earth's gravitational field, almost simultaneously registered a powerful gravitational impulse. According to GeoChange Journal, "such a phenomenon is only possible if the source of this emanation is at the Earth's core level. That huge energy release from the Earth's core at the end of last year was some kind of a start signal indicating the transition of the Earth's internal energy into a new active phase." An astronomical anomaly? A third explanation, that has not been mentioned by Dr. Khalilov, is that these unusual sounds from the sky are caused by an astronomical anomaly which scientists have not yet been able to identify. If Dr. Khalilov is correct in his assumptions, the causes of acoustic-gravity waves are of a understandable geophysical nature. However, this would also mean our planet can expect a significant increase in solar activity and geodynamic activity, which in turn results in strong earthquakes, volcanic eruptions, tsunamis and extreme weather events. We still do not know what is causing these odd sounds from the sky and although researchers have tried to explain the phenomenon in scientific terms, we are still missing an important bit of the puzzle. The sounds are heard too often and should not be ignored and dismissed as trivial. |

People around the world have reported hearing strange sounds from the skies over the past month. Sometimes they describe it as a hum or low rumble; other times it’s a whine, thump, or even a melody. Often the sounds have been recorded and posted online, fueling rumors and conspiracy theories.
One blogger wrote, "either the world is ending, aliens are landing or everyone is getting hoaxed. Or, possibly, there’s an actual scientific explanation for the mass amount of YouTube videos capturing bizarre sounds that are being heard around the globe. Are we witnessing the beginning of a full-scale alien invasion?" So, what are people hearing (and recording)? Natural Explanations The explanations are almost as varied as the sounds themselves. There's not a single blanket explanation for all the mysterious sounds, though many have been identified. For example there's the recent "midnight roar" reported in Malaysia: According to a 'Borneo Post' report, the "Sky Roar" had been heard over Kota Samarahan from around 2am or 3am till dawn on two days. Terrified residents, the report added, described the noises as a "loud hushing" or "snoring" sound. The sounds were also recorded that night, and were later uploaded on YouTube. The Minister of Science, Technology and Innovation has a very simple explanation – it was created by an oil palm factory testing their boiler pressure on Jan 11 and Jan 12. In other cases the strange sound is still being researched; last week the Canadian government was asked to investigate a low-frequency hum that has intermittently plagued citizens in Windsor, Ontario for months. (If the conspiracy theorists are right, Canadian Prime Minister Stephen Harper may soon get an unofficial visit from Men in Black-type agents warning him not to investigate.) There are a few things to keep in mind about these strange, ambient sounds; for one thing, there is virtually no place on the planet where noise pollution is not a problem. We live in a constant sea of background noise, most of it unnoticed until we start paying attention to all the sounds and focusing on them. |
Sources of indoor sounds are nearly endless, from faintly ticking clocks to air conditioning to bubbling aerators in fish tanks. Outside the problem is far worse, with noise generated by countless sources including traffic; airplanes (seen and unseen); radios; lawnmowers and snowblowers; trains; highways; and high-tension lines. Then there are the many industrial sources of noise and vibrations, including power plants and any factories with large machines such as auto assembly plants and printing presses.
Some complain that the promise of green energy offered by large wind turbines comes at a cost: a low, rumbling, rhythmic whoosh or groan that travels through the air and earth, sometimes for miles. Furthermore, the earth itself generates a natural, constant hum (though it's typically far below the threshold of human hearing). Scientists believe the hum is created by ocean waves crashing over continental shelves, which creates vibrations that travel throughout the world. Hoaxes In some cases, the "mysterious sound" videos have been revealed as hoaxes. For example, a college student in Edmonton, Canada, posted a video of mysterious sounds which got nearly 140,000 views on YouTube before she admitted it was fake. She told a local newspaper, "I made the video by taking out my iPhone and merely video recorded my balcony view while holding my laptop right behind it, while my laptop played the Conklin YouTube video in the background. Took less than a minute to do this.... I made the video to show my friends and family how easy it was (literally less than five minutes of my life to make the video and upload it) to make something like that, and how they shouldn’t believe everything they see online, and should especially not get fearful." Mysterious sounds are nothing new, of course. The most famous mystery sound in the world is probably the Taos Hum, a low-frequency rumble heard by some residents in Taos, New Mexico, since the early 1990s. Not everyone hears it, but the earwitnesses who do variously describe it as sounding like a running refrigerator or a buzzing bee. Researchers have been unable to pinpoint the source of the sound -- or even confirm that the hearers are indeed perceiving a specific, identifiable sound. While the public may assume that locating a sound is easy, it's not. Identifying the source of a sound is very difficult in urban areas where concrete, glass, and buildings can reflect, change, and amplify sound waves from ordinary sources. Of course it's more fun to think that the mysterious sounds are part of an alien invasion or secret military experiment than machinery at a local sewage plant. |
