We have mysteries around us and they leave us head scratching everytime, just taking the sound’s category, we have these ten.
10. Slow Down
” Slow Down” is a sound recorded on May 19, 1997, in the Equatorial Pacific ocean by the U.S. National Oceanic and Atmospheric Administration. The source of the sound remains unknown. The name was given because the sound slowly decreases in frequency over about 7 minutes. The sound was detected at 15°S 115°W / 15°S 115°W / -15; -115. It was recorded using an autonomous hydrophone array. The sound has been picked up several times each year since 1997. One of the hypotheses on the origin of the sound is moving ice in Antarctica. Sound spectrograms of friction closely resemble the spectrogram of the Slow Down. This suggests the source of the sound could be a friction phenomenon of ice rubbing over land. More of similar to this were recorded but later in different areas and different frequencies namely; Julia, Upsweep, and Train.
9. Electronic voice phenomenon
Caution: the recording is violent and may be too intense for some listeners.
“Electronic Voice Phenomenon” or the Phantom Words are electronically generated noises that resemble speech, but may or may not be the result of intentional voice recordings or renderings. Some have claimed these sounds are of paranormal origin, while others give explanations such as apophenia (finding significance in insignificant phenomena), auditory pareidolia (interpreting random sounds as voices in their own language) but no explanation is generally accepted. Now thousands of people across world spend their free time in wandering around haunted locations and installing recorders and video cameras in hopes of spooks and apparition. The evidence could be found at City of Dundee in Scotland, a city packed full of dead people, really a huge part of this city is formed over a massive ancient graveyard. It’s here wondering among the deceased, many EVP investigators have recorded strange findings.
” Quackers” are mysterious sounds, similar to a frog noise, widely reported by the crews of Soviet Navy submarines from various parts of the North Atlantic and Arctic Oceans during the peak of the Cold War, as well as their assumed sources. They are an example of Unidentified Submerged Objects. During the Cold War, when Soviet ballistic missile submarines went to patrol northern seas, their crews started reporting the mysterious frog-like sounds, which soon were dubbed “quackers”, from the Russian rendition of a frog noise. These sounds appeared when submarines passed certain zones in the sea, and behaved as if they were emitted by some moving underwater object, which, however, failed to register on the active sonar. When the sub left their “patrol zone”, the objects disappeared after emitting one final “quack”. These objects exhibited behavior not unlike some living being or manned vessel, showing obvious interest in the passing submarine, circling around it, trying to actively avoid sonar pulses, and so on. The speed of some of these objects (estimated from Doppler shift of their sound frequency) was in the range of 200 km/h, much higher than any then-known man-made vessel. Contact was attempted on several occasions, but, apart from some obvious reactions to these attempts such as changing the pitch of the sounds or movement of the apparent sound source), nothing came of it.
7. Sounds from Planets in Vaccum
For obvious reasons we know sound needs a medium to be transmitted then how come these sounds are possible from space where there is just vacuum, this remains unexplained. May be the scientists should reconsider the definition of sound and explain that sounds exist as electromagnetic too or may be they should redefine “space” which literally means empty? huh? And if they explain that they’re still eerie and otherworldly.
6. The Brown Note
The “Brown Note” is a theoretical infrasound frequency that would cause humans to lose control of their bowels due to resonance. During many shows on Science Channel, they broadcast the note over the air (and into the living rooms of viewers) in an attempt to cause bowel movements among those who had chosen to stay in the room despite repeated warnings and opportunities to leave. It should be noted, however, that sound at this frequency at a significant volume cannot be generated by television speakers, so you might feel only slight movements in your tummy but don’t poo. However sub-woofers might help which were used on the test subject. The explanation for this note which causes subject’s bowls to loose is not known.
