Several times in 1997, the National Oceanic and Atmospheric Administration (NOAA) recorded an unusual sound from the depths of the Pacific Ocean. The “roar” grew sharply louder and was noticeable enough for sensors located 5,000 kilometers from the epicenter of the sound to pick it up.
According to one working version, it is quite possible that the sound is made by a living creature or even a large concentration of living creatures - for example, giant squids. Judging by the distance that the sound covered, its source could also be a creature larger than a blue whale. Science does not yet know such an animal.
Taos rumble
Popular
For many years, residents of the city of Taos in the southwestern United States have been hearing low-frequency noise of unknown origin coming from the desert. Taos noise, also called Taos hum, ranks first in the ranking of the most incredible natural phenomena.
It resembles the movement of some kind of heavy equipment, although there are no railroad tracks or highways near the place where it is heard. Another peculiarity of the hum is that only local residents hear it, but tourists hear it very rarely. Scientists were unable to find the source of the hum. They only suggested that the cause of its occurrence could be power lines passing near the village.
The groan of the Earth
It is also called Sounds of the Apocalypse or Creaking of the Earth (so-so names, right?). This is a sound anomaly that was recorded in different parts of the Earth. “Moan” has been repeatedly recorded on audio media, and many people hear it.
It first appeared in 2011. All sorts of theories have been put forward about it: the most common version sounds vague: “large-scale energy processes.” This may include, for example, powerful solar flares.
Julia
Another sound of aquatic nature. Sounding like a coo or whine, it was recorded on March 1, 1999. Scientists have named it by the gentle name Julia, although it may turn out that the source of this sound is not gentle at all. The cooing was recorded by an autonomous network of hydrophones in the eastern equatorial Pacific Ocean.
"Slow Down"
On May 19, 1997, the US National Oceanic and Atmospheric Administration detected a mysterious sound. It was called “Slowdown” - due to the fact that every seven minutes the frequency of the sound decreases and it becomes drawn-out.
The "slowdown" was recorded by an autonomous underwater acoustic recorder in the equatorial Pacific Ocean. Its distribution range is 2 thousand kilometers.
Signal "Wow!"
This sound has become almost history. The sources of the mysterious hum may not only be the depths of the ocean. This was a radio signal detected by Dr. Jerry Eyman on August 15, 1977, while working on the Big Ear Telescope.
Amazed by how closely the characteristics of the received signal matched the expected characteristics of an interstellar signal, Eyman circled the corresponding group of symbols on the printout and signed on the side: “Wow!” This signature gave the signal its name.
In addition to quite prosaic theories, there is also That Same - an alien starship. And although Eyman himself was skeptical, he later revised his views, although he urged “not to draw far-reaching conclusions.” But we know...
The loneliest whale in the world
The source of this sound is well known, and the story of its origin brings tears to my eyes. It is called the 52-Hz whale. This is an unknown species of whale that appears from time to time in different parts of the ocean. It “sings” at a frequency of 52 Hz, a much higher frequency than that of the blue whale (15-20 Hz) or fin whale (20 Hz). That is, his relatives simply... don’t hear him.
The travel routes of a lone whale have no relation to the presence or movements of other whale species along its route. The whale could probably just be deaf.
Recently, scientists are increasingly receiving information about mysterious noises that are heard in different parts of the Earth, which seem to come from the bowels of the planet itself. Somewhere this phenomenon is similar to the sound of a jet engine, somewhere like a metal creaking, and somewhere like the sound of a train. Many researchers believe that the hum growing right inside the Earth may be a harbinger of an imminent change in the magnetic poles of our planet. Scientists can only assume a possible change in the planet’s magnetic poles. Maybe the planet is “groaning,” thereby warning of impending changes.
Unfortunately, there is no explanation yet for where this hum comes from. According to one of the theories of researchers of this phenomenon, the planet itself will provide more and more evidence of tension and compression of its surface. The mechanism of this phenomenon can be compared to the appearance of the hum of an airplane - the air mass is compressed, and noise appears. The hum, which can serve as a harbinger of a cataclysm, most likely arises as a result of vertical vibrations of water. This is similar to how the crust is torn apart by earthquakes.
The noise can be heard in various parts of the Earth. The latest source of such an inexplicable rumble was Kyiv. The terrifying noises were heard all day; city residents even made several videos. However, it was never possible to establish the source of this phenomenon. Various working options were put forward as possible versions - the creaking of an iron bridge, the sound from air collectors, the construction of a subway. Meanwhile, the leadership of the local government did not conduct any checks on this fact. What is most surprising is that even residents frightened by the mysterious noise refuse to write official letters to the management, believing that this issue has a mystical side, which could put them in a bad light.
Residents of London also hear a mysterious frightening hum. Inexplicable knocking noises were heard here at night. Until now, the source of these knocks has not been found. According to official reports, eyewitnesses heard five dull repeated knocks in the middle of the night. Even earplugs and double-glazed windows were no obstacle to such noise. One local resident claimed that it was comparable to someone beating a drum loudly.
Noises were also heard in early spring in Spain. The sound here was similar to the sound of a jet engine, and at the same time it also vibrated. At the same time, inexplicable sounds were heard in America. And residents of New Mexico compared the noise they heard to a truck engine idling. Before this, in Seattle they heard a noise somewhat similar to the beating of drums. Hearing such “wailing” of the planet, the Japanese assumed that this was a harbinger of another approaching earthquake, but they were mistaken.
This is how eyewitnesses describe such cases. So, one day, North Carolina resident Jodie Smith was disturbed by an unusual sound that was rapidly growing. She was not the only one who heard this sound, as Jodie ran outside and ran into a crowd of neighbors disturbed by the noise. The clear sky eliminated the possibility of thunder. Smith returned home and posted a message on Facebook asking anyone who had also heard the sounds to come forward. After a few minutes, she received a huge number of confirming responses. The authors of some messages were located at a distance of 30 kilometers from her. This was not the first time Smith herself had heard these sounds. She claims to hear such increasing sounds several times a year.
Colin Hackman, a local journalist, decided to investigate these strange sounds. However, he could not explain them by any human activity. Neither quarry explosions nor military explosions could have generated such sounds. Hackman claims that there is actually a secret hidden in these sounds.
There is a lot of evidence of a strange anomaly, and information about strange whistles, roars and explosions comes from all over the Earth. Eyewitnesses claim that this sound seems to pass through the entire body, i.e. These vibrations come straight from the depths of the planet itself. This is a fairly common phenomenon and not at all studied. Skeptics attribute everything to “rolls of thunder” and “construction noise.” And scientists just shrug their shoulders and refer to the fact that the problem has not been studied or even identified. This gives the next madmen the opportunity to contribute to the writing of a book about the Apocalypse and compare the noise with the sound of the Jericho trumpets, which herald the coming of Judgment Day.
So what is actually the reason for this strange phenomenon? Some of these sounds have obvious explanations - for example, the collapse of ocean waves or a storm. However, in many cases, no one knows the cause of such sounds, such as in North Carolina. But that doesn't stop people from offering their own explanations. If some of these theories turn out to be correct, they could change our understanding radically. Perhaps we recognize that the earth itself can make similar sounds. It must be said that mysterious sounds have a long history. For example, in Oregon there is a village called Mudus, which Native Americans originally called Machimoodus, which means “place of bad noises.”
The most likely explanation for most of the sounds is thunder. In coastal areas, the ocean can be another source of sound. According to acoustics expert Milton Garcese, there are a myriad of ways the ocean can produce rapidly increasing sounds. This is the air that is squeezed out of the wave, a huge cloud of bubbles that are present in the waves, etc. Surfers are well aware of these sounds; they are quite loud. Garcese argues that such noise can easily travel long distances over land. But these reasons do not explain what happened in North Carolina. The weather throughout the city was calm, eliminating the sounds of the stormy ocean as well as thunder.
This attracted the attention of the famous scientist David Hill. He published an article in which he indicated that all the reasons given could not explain the sounds that were heard in North Carolina. But Holm does not exclude that in the case of North Carolina, the reasons for the strange sounds were activities at a military base, which was located nearby. But he also points out that these sounds were reported by people even before the base was built.
In principle, these sounds could be explained by meteorites, since they are capable of causing a lot of noise upon entering the atmosphere, especially if something happens to them. But meteorites cannot cause sounds that are heard every few months or several years. Michael Hedlin argues that if a meteorite explosion were actually heard, it would probably only be an isolated incident. In this case, the explanation for such a phenomenon may lie in the field of geology. Dunes in some areas of the world can produce whistling, whispering, and rapidly increasing sounds. The most likely sources of these sounds are large dunes with a steep leeward slope. Exactly how sound is produced in these dunes is very poorly understood, but it is known that it requires a combination of very low humidity with loosely packed, almost spherical sand grains. Such sands are found in about thirty places. This includes California, China, Egypt, Wales. But this list does not include the Carolina coast.
Holm also put forward the theory that such sounds could be caused by a huge release of methane. Deep sea layers contain methane hydrate, and they can release methane when disturbed. This gas can explode with a very rapidly increasing sound. The problem with this theory is that it is unlikely that methane will arrive suddenly enough and in sufficient quantities to cause an explosion. This remark leaves only one reason for strange sounds - undetected earthquakes. Hill believes that a strong earthquake is not required for the sound to occur. Small earthquakes without visible ground vibrations occur all the time. Often they are only recorded by seismographs. The noise that people hear during an earthquake is actually caused by vibrations of the ground and buildings, but is not the sound of an earthquake.
However, earthquakes are accompanied by sound waves that precede the earthquake itself. We are often unable to hear this sound on the surface, since only low-frequency sound waves reach us, which lie outside the range of our perception. However, Hill says, under certain conditions, earthquake sounds can sing from the Earth. According to Hill, the ground acts like a huge bass speaker. In addition, certain weather conditions can contribute to the propagation of sound waves. But can even the weakest earthquakes go undetected? Geophysicist Jonathan Lees is very skeptical of such claims. The instruments that are used to record earthquakes are very sensitive.
But regardless of what may be causing the sounds, it seems that the Earth makes a lot more sounds than we thought. Most people are accustomed to attributing loud noises to human activity. However, the sound that is mistaken for the rumble of a truck passing in the distance may actually be the voice of our planet.
A mysterious hum coming from the sky or from underground is heard by people all over the world. This phenomenon still has no explanation and is called The Hum. It resembles the grinding of metal, as if huge mechanisms inside the hollow Earth are beginning to work...
It sneaks under the cover of darkness and once heard, you can never get rid of it again...
However, no one can determine the source of this sound and why only a certain small percentage of the population in some areas hears it. This mystery remains in the Top 10 unexplained phenomena.
The first information began to appear in the 1950s from people who suddenly began to be haunted by a low-frequency, pulsating hum.
All these unexplained cases have common details. As a rule, the hum is heard indoors at night. It is also more distinct and common in rural or suburban areas. This is probably due to the high level of general noise in urban areas.
Who hears the rumble?
Only about two percent of people hear this hum, and only in certain areas of the Earth. According to research statistics from 2003, people between 55 and 70 years old most often hear noise.
Most people who hear a hum (sometimes called "hearers" or "hummers") describe the sound as being similar to a diesel engine idling. This noise drives many people to despair.
“It can be compared to torture, sometimes you want to scream from powerlessness,” pensioner Katie Jacques Leeds told the BBC. Leeds resides in the UK, in an area where Goole has recently emerged.
“It’s worst at night,” says Jacques. “It’s hard for me to sleep because I hear this pulsating, annoying sound... I constantly toss and turn and it’s almost impossible to sleep.”
Most victims have completely normal hearing. Victims complain of headaches, nausea, dizziness, nosebleeds and sleep disturbances. There was even one suicide recorded.
Gul Manifestation Zones
The English city of Bristol is called one of the first places where Gul manifested itself. In 1970, about eight hundred people heard a haunting, persistent, buzzing noise that was eventually attributed to local factories operating twenty-four hours a day.
Another mass incident was reported in 1991 near Taos, New Mexico. Residents of the area complained of a low-frequency, almost rumbling sound. A team of researchers from Los Alamos National Laboratory was never able to figure out the sources of the mysterious sound.
Another hot spot is in Windsor, Ontario. Recently, researchers from the University of Windsor and Western Ontario University received a grant to study the Hum and determine what causes it.
Also, for several years, Australian researchers have been studying a mysterious noise in Bondi, a coastal area of Sydney, but to no avail. “This hum is driving people to madness. All you can do is turn on the music and turn it off for a while.", one of the residents told The Daily Telegraph magazine.
Returning to the United States, in 2003 the state of Indiana funded research in Kokomo. The investigation showed that one of the factories in the city, namely Daimler Chrysler, produced noise at certain frequencies. Despite the preventive work carried out, some residents continue to complain about the Gul.
What does Hum generate?
Most researchers are of the opinion that this phenomenon has real reasons and is not the result of mass hysteria or the mischief of aliens.
As with the city of Kokomo, industrial equipment is high on the list of suspects. In one case, the source of the noise was traced. It turned out to be the central heating unit.
Other researchers include high-pressure gas pipelines, power lines, wireless communication devices, and so on in the list of reasons. However, only rarely can a hum be associated with a mechanical or electrical source.
There is a theory that the hum may be the result of low-frequency electromagnetic radiation that is only audible to a small circle of people. It is likely that there are people with special sensitivity to signals outside the normal range of human hearing.
Environmental factors are also questionable. It is possible that the cause is seismic activity, in particular microseismic low-frequency tremors. And the cause of such tremors may be ocean waves.
Other hypotheses, such as military experiments or underwater communications, have not yet found evidence.
“The nature of this phenomenon has been shrouded in mystery for forty years and we may not soon know the true origin of this mystical Hum,” says the BBC.
Several years ago, the US Congress commissioned scientists and researchers from the country's most prestigious research institutions to study mysterious low frequency noise which is heard by residents in the vicinity of a small town Taos, New Mexico.
For years, those who heard this noise often described it as a "loud hum" and tried to figure out what was causing it. No one was sure exactly when the noise first appeared, but its constant occurrence first interested a few people, and then many who heard the noises joined together in a group that set out to find out what exactly was causing them. In 1993, they formally asked Congress for help.
Congress commissioned a team of a dozen researchers from some of the nation's leading scientific institutions to investigate. Joe Mullins of the University of New Mexico and Horace Poteet of Sandia National Laboratories soon submitted their final progress report.
Other scientific organizations in New Mexico also participated in the noise study, including Phillips Air Laboratory and Los Alamos National Laboratory.
At the beginning of the work, scientists suggested that the noise could be caused by manipulations by the military, but the Ministry of Defense assured that no actions or tests were taking place in this area, and until the end of the investigation they were completely open to dialogue with the team of scientists.
At the first stage of the investigation, specialists conducted a number of interviews with local residents who claimed to have heard a mysterious noise. The purpose of these interviews was to determine the nature of the noise, its frequency, time of occurrence and degree of impact on those who heard it.
The team's next step was to interview residents of the city of Taos and surrounding villages to determine how widely the mysterious sound was spreading. Finally, the research team had to try to determine the exact location and cause of the noise.
Possible sources of noise
The initial investigation focused on ten residents and it was through this that key facts surrounding the noise were identified. The hum was steady. Only a few heard it; the sound itself was low-frequency, between 30 and 80 Hz.
The noise of Taos caught on film
The researchers immediately hypothesized that, in fact, all residents simply perceived sound quite differently. Some claimed to hear a sound similar to a truck rumbling, while others heard a more sustained sound similar to a pulsation, but also described it as low-frequency.
During the research, it was possible to establish that the mysterious sound was heard not only directly in the city of Taos, but also in its surroundings. Local residents also reported physical impacts from the noise.
According to their statements and complaints, the sound caused not only irritation, but also dizziness, insomnia, high blood pressure and, in some cases, nosebleeds. Eyewitnesses were also concerned about the artificiality of the sound, which did not seem to be an ordinary natural phenomenon.
According to a report dated August 23, 1993, most residents stated that they initially heard "the humming sound was sharp at first, like something was suddenly turning on." Many of the residents were also convinced that there was a connection between the strange sounds and military installations around New Mexico.
After detailed interviews with ten local residents, the research team decided to expand their field of activity in the city of Taos. A survey of 1,440 residents revealed that approximately 2% of the city's population heard a mysterious noise constantly. Given these circumstances, the first attempts to determine the nature of the sound were associated with possible external sources for the generation of low-frequency noise, but the results of the search were negative.
In the report, Mullins and Kelly concluded that “no acoustic sources were identified during the operation that could explain the noise. Also, there were no seismic events in this area that could have caused the anomalous sounds.”
After ruling out external sources, the team focused on surveying local residents, trying to determine their sound sensitivity thresholds. Although these studies were not complete, scientists soon came to believe that low-frequency noise in the ears of local residents may be responsible for reports of strange sounds in the area.
Mullins and Kelly suggested that it is possible that local residents have developed a special sensitivity to sounds in the range from 20 to 100 Hz, and therefore they perceive constant low-frequency sounds while others do not hear them. While this approach may help answer the question of the origin of the constant hum in the area, Dr Nick Bedzic and Patrick Flanagan have also explored another possibility about the origin of the noise.
Bedzic suggested that in our time, some people have developed unique abilities to perceive noises, which have become mandatory elements of modern society. In support of his theory, he added that every day our civilization creates more and more electronic noise or background, people use more and more wireless devices, and all of them, in fact, are transmitters of electromagnetic fields.
For some reason, according to Bedzic, some of the local residents learned to hear these sounds, and they became the cause of their discomfort. But Dr. Bedzic also noted that scientists certainly cannot be sure that electromagnetic fields are the cause of the noise, and that this assumption is just another version of the possible origin of the noise in Taos.
After putting forward such theories, scientists immediately wanted to get confirmation of its correctness, and set out to conduct joint attempts to establish the truth together with local residents.
To this day, no one has been able to establish whether the electromagnetic background is the cause of the strange sounds, and the search for its source is still ongoing...
