During the last decade, bizarre sounds were heard all over the world with no possibility of denial. From strange underwater sounds, unexplained sonic booms and the so called “seven trumpets of the Apocalypse”, these bizarre sound phenomena failed to receive any satisfactory explanations from the authorities or the scientists yet.
This strange sound in Earth’s Pacific Ocean was captured by deep sea microphones in 1997. Although Bloops are some of the loudest sounds of any type ever recorded in Earth’s oceans, their origin remains unknown.
The Bloop sound was placed as occurring several times off the southern coast of South America and was audible 5,000 kilometers away. Although the sound has similarities to those vocalized by living organisms, not even a blue whale is large enough to croon this loud. The sounds point to the intriguing hypothesis that even larger life forms lurk in the unexplored darkness of Earth’s deep oceans since it was several times louder than the loudest known biological sound of the blue whale.
A less imagination-inspiring possibility, however, is that the sounds resulted from some sort of iceberg calving. No further Bloops have been heard since 1997, although other loud and unexplained sounds have been recorded (see below).
EVP – the Electronic Voice Phenomenon
Also known as the Phantom Words, EVP are electronically generated noises that resemble speech, but may or may not be the result of intentional voice recordings or renderings.
Some claim these sounds to be voices of ghosts or spirits, while others dismiss the mystery saying that EVP is nothing more than the result of apophenia (finding significance in insignificant phenomena) or auditory pareidolia (interpreting random sounds as voices in their own language) .
