Gli alieni comunicano con noi? Esistono mitoloici mostri nelle profondità marine? Le spie Russe comunicavano tramite segnali radio criptati?

Il mondo è pieno di suoni, prodotti da ogni cosa che ci circonda, la maggiorparte di questi sappiamo da dove proviene, ma esistono alcuni suoni per cui negli anni non si è mai trovata una provenienza e una spiegazione.

Ecco a voi 8 misteriosi suoni mai identificati.

1. The Bloop

Durante il 1997 i rivelatori ad alta profondità dell’istituto oceanografico mondiali, registrarono un misterioso suono, della durata di circa 1 minuto e udibile in un raggio di circa 5000km da diversi rivelatori sparsi in tutto l’Oceano Pacifico. I dispositivi, posizionati, nella zona chiamata “Deep Sound Channel” (Profondo canale dei suoni) durante la guerra fredda, avevano lo scopo di captare segnali provenienti dai sottomarini Sovietici e sono tuttora utilizzati per monitorare fenomeni naturali. Il suono nelle registrazioni, cresce repidamente di frequenza per poi scomparire lentamente nelle profondità dell’Oceano. Si esclude categoricamente che il suono possa essere stato prodotto dall’uomo o da qualche animale conosciuto, anche dell’epoca preistorica. Si ipotizza che possa provenire da qualche sconosciuta creatura delle profondità marine.

1. The Hum

In tutto il mondo, in luoghi come il New Mexico, le Hawaii, la Gran Bretagna, nel corso degli anni, varia persone hanno descritto e sentito quello che viene chiamato il suono dell’Hum.

L’Hum è un suono persistente, fastidioso e molto simile a quello del motore di un’auto in lontananza e che spesso viene percepito attraverso vibrazioni al’interno del corpo (come quelle che si provano davanti a delle casse ad alto volume). A detta di chi ha sentito questo rumore, il suono non può essere registrato in modo accurato dai microfoni e si propaga con più intensità durante la notte e con maggiore presenza durante la fine della settimana.

Nell’isola Big Island delle Hawaii, il suono è attribuito al vulcano, ma molti obiettano che il medesimo suono non può essere attribuito ad un vulcano anche a Kent, in Inghilterrao a Taos nel New Mexico.

E’ un effetto dell’elettromagnetismo? Supernaturale? Una illusione collettiva? Al momento è possibile dirlo.

Bizarre Booms

“Mistpouffers” – it’s a funny name for a series of bizarre booms that have been heard in waterfront communities ranging from Bangladesh to the Netherlands, typically described as a cannon sound or extremely loud thunder despite the absence of clouds in the sky. It’s frequently heard on calm summer days in the Bay of Fundy, Canada and has also been reported in Italy, Ireland, India, Japan, the Philippines, Ireland and in several U.S. States. These booms are no modern invention – the Iroquois explained similar noises to early white settlers as the sound of the Great Spirit continuing to shape the earth.

In 1978, a boom heard on Bell Island off Newfoundland in Canada was powerful enough to damage homes. While some may still believe that it was caused by supernatural phenomena and a recent History Channel special questioned whether secret electromagnetic pulse weapons tests could be the culprit, the cause is still a mystery.

In May 2010, bewildered Pennsylvania residents contacted the local paper about a “big boom”. “I heard the boom, and my closed, wooden front door rattled just a little bit,” Kim Owen told the Sun Gazette. “I didn’t think much about it until a friend, who lives several blocks away, posted a note on Facebook asking if anyone had heard a loud boom.” A similar noise in 2001 later proved to be caused by a meteorite crashing through the earth’s atmosphere.

It could be that these sounds are all caused by meteorite impacts, but other natural causes are possible as well including gas escaping from vents in the earth’s surface or underwater caves collapsing.

The ‘Slow Down’ Sound

Recorded on May 19th, 1997 – the same year as ‘The Bloop’ – this unexplained sound is seven minutes long, slowly descending in frequency toward the end. Known as the ‘Slow Down’ sound, it was loud enough to be heard on three sensors at a range of nearly 2,000km. Nothing like it has been heard ever since, and its origin remains unexplained, landing it on the NOAA’s short list of strange unidentified noises picked up by their undersea microphones.

During the Cold War, as Soviet Navy ballistic missile submarines patrolled the North Atlantic and Arctic Ocean, they kept hearing the strangest sounds: what they described as “quacking”, the Russian version of our own onomatopeotic “ribbit” of a frog. The sounds were heard whenever the subs passed certain areas of the sea and seemed to be coming from a moving underwater object. However, nothing registered on sonar.

The Soviets believed at the time that they were hearing some kind of secret U.S. Technology and interpreted the sounds as a somewhat frightening threat. Today, scientists believe the sounds may have come from marine life like giant squid, which – lacking rigid internal skeletons – might not show up on sonar.

The Spooky Sounds of Saturn’s Rings

They’re eerie and otherworldly, exactly the kinds of bizarre noises you would expect to hear in a sci-fi film – but they’re actually real recordings from another planet. The Cassini spacecraft began detecting these auroral radio emissions from Saturn’s atmosphere in 2002, which have natural rising and falling tones similar to those emitted by Earth. The NASA recordings have been compressed and compiled into this single spooky track, and it’s all too easy to imagine all kinds of things within them, from alien speech to a spacecraft taking off.

The UVB-76 Buzzer

It seems like a mystery worthy of LOST – a strange repeating radio signal from Russia, punctuated by occasional cryptic messages in Russian. Short, monotonous buzzing tones have been emitted 25 times per minute, 24 hours a day since 1982, and nobody knows exactly why. Perhaps it’s used to transmit encoded messages to spies, or signal the status of some undercover military installation. Or, maybe it’s just related to high-frequency Doppler weather radar.

The voice messages transmitted by this signal, which have occurred only three times in 1997, 2002 and 2006, have all been numerical in nature. One features a Russian male voice saying “”Ya ? UVB-76. 18008. BROMAL: Boris, Roman, Olga, Mikhail, Anna, Larisa. 742, 799, 14.”

On Sunday, June 6th, 2010, a commenter on Slashdot wrote, “Tinfoil hatters around the world are abuzz that UVB-76, the Russian shortwave radio station that has been broadcasting its monotonous tone almost uninterrupted since 1982, has suddenly gone offline. Of course no one knows what the significance of this is, but best brush up on your drills just in case.”

The ‘Wow’ Signal

Did aliens try to contact us with an interstellar signal detected in 1977? The strong narrowband radio signal picked up by The Big Ear telescope of Ohio State University lasted for a total of 72 seconds and matched the expected signature of an interstellar signal, prompting Dr. Jerry Ehman to circle the signal on a printout and write “Wow!” beside it.

There’s no question that the signal originated from outside of our solar system, and in fact, its origin has been pinpointed as somewhere beyond the constellation Sagittarius. It was picked up by only one of the Big Ear’s two detectors and was never heard again despite close monitoring, but all “rational” explanations put forth by skeptics have been proven wrong, from satellite transmissions to space debris collisions.

The Wow! Signal is still the only confirmed sound received from deep space that could possibly be an intentional signal sent by entities unknown.
