Do you have an idea about what could be these humming sounds heard in Rosario, Argentina?
There weird and high-pitched noises from the sky are baffling! They sound like a siren to me!
These strange humming noises were captured at 00:00pm on February 26, 2012 in Rosario, Argentina.
The recorder explains it’s the fourth time he hears this annoying noise which started approximately 1 month ago. Each time, it lasts about 10 to 15 minutes except this time which was about 5 minutes long.
The humming sound is very strong and baffling. It is a kind of hearing effect (tinnitus?). One cannot locate a source, as if it was coming from everywhere!
What do you think?
