A strange trumpet noise from the sky is continuing to confuse people all around the world. Experts have no clue what might be causing it. The strange sounds have been constantly heard at different locations for almost 10 years.
People who were able to capture the unfriendly sound uploaded their recordings on social media sites. Many of these clips came from the United States, Germany, Australia and Canada, Daily Mail reported.
In Canada, Kimberly Wookey was able to record several clips of these strange sounds, according to Mirror. Wookey uploaded many of the clips on Youtube.
She said that this is the second time she has heard these noises in Terrace, BC Canada. She further said that she heard the sound for the first time on June 19, 2013 at 9-9:30am; however, it was not quite as intense.
Aaron Traylor, a Montana resident, said that he had been having bad dreams after he uploaded the eerie sounds.
NASA researchers believe that the sound could potentially be the background noise of our planet. A NASA spokesperson explained that if people had radio antennas, they would hear an amazing symphony of unusual sounds coming from the Earth.
According to the space agency, the sound can be compared to the background music that can normally be heard in science fiction films. However, experts said that the sound coming from our planet is not science fiction.
NASA said that the natural radio emissions from the Earth are real. Many are not aware of this phenomenon, but the sounds happen around people all the time.
