What is the source of these weird humming sounds heard over Manchester and Blackburn, UK?
A sign of the upcoming apocalypse? Alien communication? A hoax? Electromagnetic currents?
Its true, this strange sounds phenomenon has sparked a fierce of debate since it has started back in 2008.
It is not only present in large cities (car noise?) but can also be heard in smaller towns such as Blackburn in the UK as shown in the following video:
What are the origin of the hum?
First theories assign these strange noises to High Frequency Active Auroral Research or HAARP.
Others try to explain them as electromagnetic noises emitted from auroras and radiation belts.
Finally these strange humming noises could be related to mating fish.
Yet conspiracists and religious figures have painted a much worrying picture and are adamant that the noises could signal the end of the world or ‘The Second Coming’ or even God’s angels blowing in their aopcalyptic trumpets!
What is the Hum?
According to scientists, most of the hum spectrum is not audible to humans. It is only a small fraction of the actual power of these low-frequency sounds.
As already shown in a previous article, causes of these sounds can be earthquakes, volcanic eruptions, hurricanes, storms and tsunamis, however the scale of the observed humming sound in terms of both the area covered and its power far exceeds those that can be generated by the above-mentioned phenomena.
Whatever the reason, the source of the Hum is still unknown. In some cases, government even paid universities to figure out the source of these strange sounds getting people crazy. But, until now, without any success.
