I've tried twice to reply to this thread and twice Mozilla has locked up and not let me. Very strange...
Here goes again:
First, I noticed many You-Tube comments about it being "whales", so I googled and played some whale song sounds. They are much higher-pitched; whatever these are, it isn't whales.
Secondly, my son, (whom some of you may remember is blind) is an accomplished musician with perfect pitch. He came into the room while I was playing this video, and said (not being able to see the screen), "Who's playing the horns?" I didn't answer, because I wanted to get his reaction as to what it sounded like, since he's so attuned to music of all kinds and sensitive to sounds, and I thought he might be able to recognize what it might be. He said it sounded like very deep horns, and asked if it was a lighthouse horn or a fog horn (I only said no and didn't elaborate), and then I asked him what pitch the sounds were. He said the higher tone was a D above high C, the mid-tone a G above middle C, the next-lower tone (and the one that sounded the most) an A-flat, and the very low tone a low C. He said some of the tones were so low he couldn't clearly identify the pitch.
Finally:
I don't mean to scare you guys to death, but those sounds have been heard and recorded in historical documents before:
As one scientist wrote, they tend to precede, or accompany:
either earthquakes
or
"the approach of two charged globes toward each other."
Quoting from Emmanuel Velikovsky's seminal work, Worlds In Collision:
Chapter 4, Section 3: Theophany (the sound of God)
"Earthquakes are often accompanied by a roaring noise that comes from the bowls of the earth. This phenomenon was known to early geographers. Pliny wrote that earthquakes are "preceded or accompanied by a terrible sound." Vaults supporting the gorund give way and it seems as though the earth heaves deep sighs. The sound was attributed to the gods and called theophany...
In the days of the Exodus, when the world was shaken and rocked, and all volcanoes vomited lava and all continents quaked, the earth groaned almost unceasingly. At an initial stage of the catastrophe, according to Hebrew tradition, Moses heard in the stillness of the desert the sound which he interpreted to mean: "I am that I am" (for which the Hebrew lettering is YWHW, variously pronounced Yahweh, Yahovah, Jehovah, etc.--note mine)...
"I am Yahweh," heard the people in the frightful night at the Mountain of the Lawgiving. "The whole mount quaked greatly" and "the voice of the trumpet sounded long." And all the people saw the roars, and the torches, and the noise of the trumpet, and the mountain smoking: (remember the hill "smoking" in California?--note mine) and when the people saw it, they trembled, and stood afar off."...
(V. goes on next to summarize again the earth changes brought about by the near-miss of earth with another large celectial object, which he believes was a large comet, and which he believes accounts for the many descriptions in ancient Egyptian, Sumerian, and Grecian mythology of the "wars in the heavens" between "gods" and a "serpent" or "dragon" that was attempting to "eat" the sun or destroy the earth, and which he also believes caused the physical effects on earth described in the Bible during the plagues of Egypt and the Exodus)
The earth groaned; for weeks now all its strata had been disarranged, its orbit distorted, its world quarters displaced, its oceans thrown upon its continents, its seas turned into deserts, its mountains, up heaved, its islands submerged, its rivers running upstream---a world flowing with lava, shattered by meteorites, with yawning chasms, burning naphtha, comiting colcanoes, shaking ground, a world enshrouded in an atmosphere filled with smoke and vapor. Twisting of strata and building of mountains, earquakes and rumbling of volcanoes joined in a n infernal din. It was a voice not only in the desert at Sinai; the whole world must hae heard it...
The approach of two charged globes toward each other would also produce trumpetlike sounds, varying as the distance between them increased or lessened. It appears that this phenomenon is described by Pseudo-Philo as "testimony of the trumpets between the stars do their Lord. Here we can trace the origin of the Pythagorean notion of the 'music of the spheres' and the idea that stars make music...
Homer describes a similar occurrence in these words: "The wide earth range, and round about great heaven pealed as with a trumpet.
"The world all burns at the blast of the horn," is said in the Voluspa.
According to the Hebrew tradition, ALL the nations heard the roaring of the lawgiving. It appears that at Mount Sinai the sound that "sounded long" rose ten times, in this roaring the Hebrews heard the Decalogue:
"Thou shalt not kill" (Lo tirzah)
"Thou shalt not commit adultery" (Lo tin'af)
"Thou shalt not steal" (Lo tignov)...
The din also caused by the groaning earth repeated itself again and again, but no so loud, as subterranean strata readjusted themselves after being dislocated; earthquakes incessantly shook the ground for years. The Papyrus Ipuwer calls these years "years of noise." "years of noise. There is no end ot noise," and again, "Oh, that the erath would cease from noise, and tumult be no more."...
The sound probably had the same pitch all over the world as it came from the deep interior of the earth, all of whose strata were dislocated when it was thrown from its orbit and forced from its axis...
The great king-lawgiver of China, in whose time a dreadful cataclysm took place and the order of nature was disturbed, bore the name Yahou....Yahou was a surname given to him in the time following the flood, apparently inspired by the sound of the earth's groaning...
The same sound was heard in those years in the Western Hemisphere...wherever the ancestors of the Indians then lived. They relate that once when the heavens were very close to the earth, all mankind lifted the sky little at the repeated shouting, "Yahu," which rang all over the world...
In Indonesia, an oath is accompanied by the invocation of the heavenly bodies. An arrow is shot toward the sky, "while all present raise a cry of 'ju ju huwe.'"
The same sound is heard in the very name Jo, Jove (Jupiter). The name Yahweh is preserved in shorter forms, as well, Yahou and Yo, as the name of the Deity of the Bible...
In Mexico, Yao or yaotl is the god of war...
Nihongi, the chronicles of Japan from the earliest times, begins with a reference ot he time when "of old, heaven and earth were not yet separated...The time when the sky touched the earth is the time when the heavy dust and vapor-charged clouds of the comet enveloped the globe and lay very close to the ground...
The history of China...of these few remains of the old lore, the most cherished are those which tell of the Emperor Yahou and his times..."At that time the miracle is said to have happened that the sun during a span of then days did not se, the forests were ignited, and a multitude of abominable vermin was brought forth...In the lifetime of Yaho (Yahou) the sun did not set for ten full days and the eatire land was flooded..."

"If" this sound is NOT man-made or produce d by a man-made machine, then I would not be surprised if one of the two above-given explanations for the "sounds" accounts for what we are currently hearing.
After all, we are told in Romans 8:
For we know that the whole creation groans and suffers the pains of childbirth together until now. --
and look at the whole passage from which that verse comes:
For the anxious longing of the creation waits eagerly for the revealing of the sons of God. 20For the creation was subjected to futility, not willingly, but because of Him who subjected it, in hope 21that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. 22For we know that the whole creation groans and suffers the pains of childbirth together until now. 23And not only this, but also we ourselves, having the first fruits of the Spirit, even we ourselves groan within ourselves, waiting eagerly for our adoption as sons, the redemption of our body.
