Are The Strange Sounds Heard Worldwide A Mass Viral For Mass Effect 3??

The important part of this video is the 2:15 mark. That is when you hear the sound that the reapers make. The reapers in the game are these creatures that are trying to invade the Earth. The sound that they make is very similar to some of the strange sounds that have been heard around the world. Could this be a mass viral campaign for the video game? Only time will tell.
