Hello, today I bring you a mystery that remains unsolved to the hum you provided here you have a bit of information:

                                                                                                                                  The hum

the hum or buzz is a strange metallic noise you do not know where it comes from , in some cases listen better inside than out and about and not everyone can hear it as it is an ultra-low frequency
1st . - The international scientific researchers Agency Wosco say the ' HUM ' could be caused by the sharp increase in solar activity and the intensification of energy processes in the Earth's core , registered lately .

2nd . 'Another theory refers to the process of absorption in the resonant cavity of the Earth: The sound of Schumann resonances as a result also of the processes of interaction with the energy coming from solar storms.
3rd . , Other speculations are based on our solar system, which focuses on protecting the heliosphere , is being ' rubbed ' by something invisible or an " interstellar cloud." This cloud could belong to a nearby solar system, near to ours , causes strange noise and causes a lot of anomalies on the planet and bodies that roam in our solar system.
4th . , Not forget that were recently detected a series of changes that led to the death of birds, fish , whales and dolphins. For proponents of this hypothesis Hum , come from experiments under HAARP or DARPA , military weapons projects generation .
5th . - One version that expose the researchers is that the magnetosphere has lost potential to dampen solar radiation capacity , so that gaps are created causing the solar energy input to our planet, pure and forceful manner , causing noise could be due to tearing of the protective shield.
Now look at this newspaper :

Geophysicists say they have discovered the origin of the mysterious phenomenon known as ' the sound of the Apocalypse ' or ' HUM ' , the dull hum at low frequencies is listening on different parts of the world since the middle of 2011 .
                     We started badly. The Hum comes from long before the summer of 2011. Data from at least the late 70s , when in Bristol more than 800 people said they could hear an annoying buzz. At the time, those coming to the conclusion that they had a regular source sounds were analyzed . Specifically , traffic noise or nearby factories machinery . What does dating from the summer of 2011 , is the video of the trumpets of Kiev ChrisTef uploaded to youtube by a computer geek.

                                We have analyzed these sound recordings and have found that most of their spectra fall in the infrasound , which is inaudible to humans. What people hear is only a fraction of the power of these sounds. Are low frequency acoustic emissions in the range of 20 to 100 Hz modulated ultra low 0.1 to 15 Hz are called infrasonic waves geophysical gravitational acoustic waves. They are formed in the upper atmosphere.

But back to the phenomenon of tinnitus , it is important to mention that it has nothing to do with the sounds of the apocalypse or anything that sounds like trumpets. The hum is more like the sound of a diesel engine idling. There is a long history of famous cases of " hum " as the 90 in Taos, New Mexico , or June of last year in Woodland, although there are many more. The origin remains a mystery .But how does it sound really " hum "?There are a number of features that recur in most cases, as the buzz is more audible at night than during the day. Not everyone can hear it. It is a very low frequency sound , which can be a pain for those who suffer . In some cases it is best heard in the house it was. Some people even feel the vibration in the body .

American archaeologists discovered in southern Egypt the tomb of a pharaoh hitherto unknown. His name Senebkay and ruled 3700 years ago, according to the Ministry of Antiquities of Egypt.

The tomb is located in the Egyptian city of Abydos. He found a group of archaeologists from the University of Pennsylvania led by scientist Josef Wegner . Experts say the discovery is evidence that this part of Egypt was not invaded by the Hyksos , a nomadic tribes of Asia.

According to the Department of Antiquities of Egypt, both in the sarcophagus and the walls of the cartridge where the actual tomb was inscribed the name Senebkey found . Archaeologists also discovered the skeleton of the pharaoh , whose height was supposed to be about 185 centimeters.

" The royal family of Abydos could have fallen Senebkay was of Egyptian origin and was not under the dominion of the Hyksos ," the Ministry said , noting that this finding may lead to future discoveries related to the royal dynasty .

Wegner told NBC News that the finding could point the way to a hitherto unknown pharaonic dynasty . "We have found an unknown king of a lost dynasty. Likely that the 16 kings are buried here. Grave now have the first or second king of this dynasty . Should be others ," he said .

Archaeologists say they were surprised to find this tomb as they were excavating and studying the tomb of another pharaoh. Last week the team of archaeologists was able to establish the identity of this ruler named Sebekhotep I. It is believed this was the founder of the dynasty XIII of Egypt 3,800 years .
