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.
