In the most mysterious on our planet, the Mariana Trench underwater the device recorded a strange sound, very passable at a moan. And although this fantastic “monster sigh” lasted only three seconds, it is struck by its very low tone within the frequency range of 38 Hz – 7.5 kHz, and also very similar to the voice of a living being.
Researchers of the ocean depths recorded this “moan” near from guam. They claim that something similar has already been recorded in this area in the fall of 2014 and spring of 2015. And this year the sound began to be repeated throughout the year, and underwater instruments fix it not only at such low frequencies as demonstrated the last record (see and listen below), but and at very high frequencies, which is not typical, for example, for whales (the first suspicion fell on them).
True, as scholars make a reservation, sleep is “metallic” high minke whales can talk to each other, however and these whales communicate in this way only in winter – during mass mating. And here all year round someone moans under water … in any case, the whale’s voice is not very similar to that of the depths of the Mariana Trench.
So who (or what) is making such eerie sounds there? Yet one riddle from the many others that our planet is full of …
