Variously described as groaning, metallic, clashing, clanging and trumpet-like, these (usually loud and pronounced) noises seem to come from the sky but generally reverberate in such a way that listeners are unable to make out from which general direction they come.
These 'strange sky sounds' have been observed all over the globe and first really caught the public's attention in 2011, when a spate of events sparked such widespread interest that significant effort was made to discredit the phenomenon through the dissemination of fake recordings.
Some, certainly, are hoaxes. That's human nature; we mock that which we do not understand. But the sheer proliferation of 'strange sound events' in recent years, the similarities (with minor differences) between them, and the diversity of the locations they've been recorded in (sometimes more than once), speaks to there being a global reality to this phenomenon. In the course of tracking and reporting these events on SOTT, we've noticed that they tend to come in waves; there can be 'silence' for some time, then 4 or 5 'strange sounds' events occur in disparate locations (perhaps within the same region or continent) in the time span of a week or fortnight. And, as best we can tell, this trend seems to be increasing.
Here is our 'best of' strange sounds summary video, comprising some events from around the world in 2016. Please excuse the occasional foul language - muting or otherwise distorting it would have interfered with the strange sounds themselves. Besides, hearing them curse and swear, you get a real sense of the observers' astonishment!
Our best guess for now is that these sounds are some kind of transduced extra-low frequency radio waves or infrasound, which we wouldn't normally be able to hear if it weren't for some relatively recent environmental changes, perhaps - in part - changes in Earth's upper atmosphere. These waves seem to interact with other electromagnetic factors in, on and around the planet, causing them to be amplified and converted into audible sound waves.

Besides just hearing these sounds, there have been several reports of accompanying physical and psychological effects on eyewitnesses.
One person, after hearing these sounds in February of 2012, claimed that he had nightmares for days afterwards, saying:
I don't recall dreaming about aliens, nor about 2012. Nothing like that. It was more so about the circumstances of yesterday's event and how I felt enormous pressure from the community to maintain my integrity. It was as if a hundred voices had questions all at the same time - people yelling in my ear saying that I was lying, or that they were frightened and wondering where they needed to go for their family's safety. It all became so much that I had to start yelling back. And that's when I woke up.In March of 2014, another eyewitness reported that he became "sick to my stomach" after walking outside to listen to the noise. Another reported, after hearing these sounds in October of 2010, having an 'out of body experience' that made them physically ill, including a sensitivity to 'electrical noise'. The effects on this person's health were such that they sought medical treatment. Another reported a "heavy headache" after hearing these sounds in August of 2012, and experienced "waves of heat" in his body for "almost 3 hours". Another reported that her head hurt during the event she experienced in March of last year.
Along with understandable anxiety and stress from hearing these bizarre sounds, these eyewitnesses could be experiencing a physical reaction to infrasound, which can literally make people sick (headaches, nausea, dizziness) and have other adverse health effects. A 2004 study demonstrated that a person exposed to infrasound can experience headaches, and feel tired and fretful; exposure can also cause changes to blood pressure and heart-rate.
At a 2003 British Association science conference, scientists report some effects and reactions to low frequency sound waves embedded in music:
Lord and Wiseman played four contemporary pieces of live music, including some laced with infrasound, at a London concert hall and asked the audience to describe their reactions to the music.One of the pioneers of infrasound research was French scientist Vladimir Gareau, whose staff experienced inexplicable ear pain and nausea while doing robotics research. This discovery led to a more nefarious exploration into infrasound and infrasonics. You can read more about it in the book, Sonic Warfare: Sound, Affect, and the Ecology of Fear.
The audience did not know which pieces included infrasound, but 22 percent reported more unusual experiences when it was present in the music.
Their unusual experiences included feeling uneasy or sorrowful, getting chills down the spine or nervous feelings of revulsion or fear.
"These results suggest that low frequency sound can cause people to have unusual experiences even though they cannot consciously detect infrasound," said Wiseman, who presented his findings to the British Association science conference.
New, but old
What we do know is that there are historical accounts by ancient chroniclers of 'strange sky sounds' that contain similar descriptions to what people are hearing around the world today. A Book of Prodigies: After the 505th year of Rome, for example, by Julius Obsequens, who wrote:
Consulship of Tiberius Gracchus and Manius Iuventius - BC 163Here's another one:
At Capua the sun was seen by night. On the Stellate Plain part of a flock of wethers was struck dead by a thunderbolt. At Tarracina, male triplets were born. At Formiae two suns were seen by day. The sky was afire. At Antium a man was burned up by a ray of light from a mirror. At Gabii there was a rain of milk. Several things were overthrown by lightning on the Palatine. A swan glided into the temple of Victory and eluded the grasp of those who tried to capture it. At Privernum a girl was born without any hands. In Cephallenia a trumpet seemed to sound from the sky. There was a rain of earth. A windstorm demolished houses and laid crops flat in the fields. There was frequent lightning. By night an apparent sun shone at Pisaurum. At Acere a pig was born with human hands and feet, and children were born with four feet and four hands. At Forum Aesi an ox was uninjured by flame which sprang from its own mouth.
Consulship of Gaius Marius and Lucius Valerius - BC 100Without a doubt, these sounds are mysterious. As far as 'the hard science' goes, they are begging for real scientific study (like so many other phenomena, both 'new' and 'known'), and not to just be dismissed as 'quackery'. We live in 'interesting times', when the dominant public discourse is often completely fake - that is, 180° reversed from reality. With such 'omens', Mother Nature is apparently asking humanity to reconsider more than just our faith in the socio-political reality as dictated by the established authorities, but the very boundaries of what is and is not 'real'...
A blazing meteor was seen far and wide at Tarquinii, falling in a sudden plunge. At sunset a circular object like a shield was seen to sweep across from west to east. In Picenum houses were flattened in pieces by an earthquake, while some, torn from their foundations, remained standing out of plumb. A clash of arms was heard from the depths of the earth. Gilded four-horse chariots in the Forum sweated at the feet. The runaway slaves in Sicily were butchered in battles.
~ From Pliny's Natural History II. 34 
We're including here an excerpt from Chapter 29 of the book Earth Changes and the Human-Cosmic Connection, researched and written by our colleagues, which looks into these strange sounds in more detail:
While we've abbreviated these sounds to 'sky sounds', it's actually unclear where they are coming from. Eyewitnesses generally describe them as emanating 'from the sky' or 'from the ground', i.e. underground. They are brief, lasting just a few minutes at a time; and they are localized, though they appear to occur in diverse locations simultaneously or in clusters.Further viewing
One of the few scientists quoted on the topic in the media is Elchin Khalilov, an Azerbaijani geophysicist:In our opinion, 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.While Khalikov is certainly onto something, he's also leading the reader astray by blaming these strange sounds on "the surge in solar activity as manifested in the higher number and energy of solar flares since mid-2011." Note that Khalikov refers to solar flares, not sunspots. So let's check solar flare activity in recent years.
Given the surge in solar activity as manifested in the higher number and energy of solar flares since mid-2011, we can assume that there is a high probability of impact of the substantial increase in solar activity on the generation of the unusual humming coming from the sky.
As shown in the image above, solar flare activity has (timidly and erratically) increased since 2011 (green vertical line), although, as we've already seen, we're in an unusually weak solar cycle (SC24) that was preceded by another weak cycle before it (SC23).
Strange sounds have been reported since 2009. Since then, there have been between 0 and 450 solar flares per month. If, as stated by Khalikov, the increase in flare activity is the cause of strange sounds, why then were they not reported in 2000 when monthly solar flare activity ranged between 400 and 800?
In addition to pointing to the wrong cause, Khalikov does a major disservice by implying that the Sun is unusually active at this time, when the truth is just the opposite.
However, "[the destabilization of] the magnetosphere, ionosphere and upper atmosphere" mentioned by Khalikov appears to be a valid and useful observation. These 'strange sounds' do appear to be some form of electrophonic phenomenon.
These are not acoustically propagated sounds, such as those heard seconds or minutes after the sighting of a meteor fireball. Also, electrophonic sounds shouldn't be confused with electrophonic hearing, which is due to the passage of an electric current (of a particular frequency and intensity) through the human body.
Electrophonic sounds were first described by astronomer Edmund Halley who collected accounts of the large 1719 meteor fireball that was observed over England. Numerous witnesses reported hissing sounds as the fireball passed, as if it had been very close by. But according to Halley's triangulation calculations, the fireball passed 60 miles overhead. At this altitude, sound takes about five minutes to reach the Earth's surface. So how was it possible to explain the fact that witnesses simultaneously heard and saw this meteor? Halley dismissed this as sheer fantasy on the part of the eyewitnesses', due to 'an affrighted imagination', and his conclusion became scientific consensus for centuries, despite recurring observations of electrophonic sounds accompanying meteor fireballs.
During the 1940s, some scientists started reconsidering the problem in terms of physics, and by the 1980s Australian physicist Colin Keay demonstrated that fireballs can indeed produce electrophonic sounds. Keay found that, in addition to generating light, fireballs also emit very low frequencies (VLF), which travel at light speed, hence the simultaneous visual and auditory perceptions reported above. In 1988, Watanabe et al achieved the first detection of a VLF signal from a meteor fireball.
These VLF are due to turbulences generated in the geomagnetic field (i.e. Earth's magnetic field) by the magnetic influence of the fireball. This is not a mechanical phenomenon, but an electromagnetic one: the fireball not only creates turbulence in the surrounding air (i.e. a sonic boom), but also electromagnetic radiation, which creates turbulence in the surrounding geomagnetic field (VLF). VLF radio waves cannot be heard by humans, of course. However, VLF sound waves match part of the normal human auditory range.
The electrophonic sounds produced by meteors are usually reported as a hissing or crackling sound; however, they can cover a whole variety of sounds and frequencies. Keay demonstrated in lab experiments how meteors could generate VLFs and also how these VLFs could be then transduced into audible sounds. The human body itself can act as a transducer, but external transduction enabled by a nearby object (like a pair of glasses or an antenna for example) is more effective than transduction occurring within the ear.
The previously mentioned 'opening up' of the Earth can be the source of electrophonics. Most of the Earth's crust can become highly conductive if subjected to mechanical stress/shock, and this high conductivity might very well produce turbulence in the electromagnetic field of the Earth, both underground and in the atmosphere. Maybe when rocks 'wake up', they don't just sparkle and glow as indicated by Freund, maybe, under the right circumstances, they also sing?
This would explain why numerous testimonies state that the sound 'came from ground level' or from several locations or from a nearby location, or from the sky, or 'everywhere and nowhere'. Keay also mentions that people's sensitivity to electrophonic sounds is variable, perhaps explaining why some people report hearing an electrophonic sound and others don't, despite being present in the same location.
Some fundamentalist Christians identify these sounds with the 'Trumpet of Jericho'. Actually, this last explanation may hold a grain of truth, particularly if the story of Jericho records a mythicized meteoric event. In such a scenario, meteoric or seismic electrophonic sounds might have eventually come to be remembered as 'trumpet-like', and the subsequent destruction of the walls of the city due to cometary bombardment-induced earthquake and fire might have later been transformed in the biblical narrative into an attack by the Israelite army.
The Old Testament's Jericho is not an isolated example. From John's Revelations to Ovid's Metamorphosis, the New Testament's Acts, Homer's Iliad, chronicles of the Ancient Roman Empire, and numerous myths and legends, ancient and historical accounts have associated blasting horns and trumpets with mass destruction."...still they gave no uncertain portents of the woe that was at hand. They say that the clashing of arms amid the dark storm-clouds and fear-inspiring trumpets and horns heard in the sky forewarned men of the crime..."
~ Ovid, Metamorphosis, Book 15 (8 AD)"They fell on one another with a mighty uproar - Earth groaned, and the spacious firmament rang out as with a blare of trumpets."Often associated with such sounds were images of 'fire-breathing' dragons and gods bringing death and destruction with their thunderbolts, rocks, fire and brimstone. As shown by astrophysicists Clube and Napier, among others, these are most likely depictions and memories of ancient encounters with comets, from a time when such heavenly occurrences were much more frequent and dramatic.
~ Homer, Iliad, Book XXI
In addition to eerie noises, electrophonics may also trigger mutations within living creatures, including humans, even in the absence of mutagenic radiation, as explained in the following excerpt from a study of the 1908 Tunguska event:Some genetic anomalies were reported in the plants, insects and people of the Tunguska region. Remarkably, the increased rate of biological mutations was found not only within the epicenter area, but also along the trajectory of the Tunguska Space Body (TSB). At that no traces of radioactivity were found, which could be reliably associated with the Tunguska event. The main hypotheses about the nature of the TSB, a stony asteroid, a comet nucleus or a carbonaceous chondrite, readily explain the absence of radioactivity but give no clues how to deal with the genetic anomaly. A choice between these hypotheses, as far as the genetic anomaly is concerned, is like to the choice between 'blue devil, green devil and speckled devil,' to quote late Academician N.V. Vasilyev. However, if another mysterious phenomenon, electrophonic meteors, is evoked, the origin of the Tunguska genetic anomaly becomes less obscure.In conclusion, alongside atmospheric dust, surface impacts, overhead explosions, electromagnetic pulses and airborne viruses, electrophonic sounds are another documented effect of meteors.
As noted, meteors are not the only phenomena that can generate electrophonic sounds. Earthquakes, lightning and Northern lights (Aurora Borealis) have been shown to be sources of electrophonics also. They display a strong electromagnetic activity that explains the disruption of the geomagnetic field and the emission of VLF. More globally, any significant change in the electromagnetic environment of the planet might induce turbulence in the geomagnetic field.
The association between electrophonic sound and disasters in general (and cometary activity in particular) has been repeatedly mentioned in ancient texts. It seems that what we are currently experiencing is nothing new; just another wave of cosmic changes and subsequent earthly destruction.
And, once again the elite rulers are trying to depict this phenomenon as man-made, harmless and unrelated to anything else of any import, whereas these sounds are in fact intimately related to the ongoing cosmic changes and are associated with very destructive natural events.
