Mysterious sounds trigger something primitive in our brains. They take us right back to our hunter-gatherer days, when deciphering a weird ‘bloop’ in the jungle might have helped us survive (as it may be a new type of predator). While that’s hardly the case anymore, that part of the brain still works the same way.
Mysterious sounds still pique our interest in a way that other senses don’t. There’s something plain creepy about a sound whose origins you can’t completely ascertain, made even creepier by just how many sounds there are nowadays; from classified radio signals to industrial machines most of us haven’t even heard of. Most of them, however, could be explained by ‘everyday things making everyday noises you just hadn’t noticed before’.
It gets weird, though, when a sound is heard multiple times by multiple people, and none of them can establish where it’s coming from. Some of the most bizarre sounds we’ve ever heard still remain unexplained, despite entire sections of the Internet dedicatedly looking for their origins.
