There’s no doubt that certain sounds have the ability to terrify us, especially those that are captured from horrifying, real-life situations.
Audio has the power to evoke an emotional response in humans — a deeply ingrained instinctive response. Hearing stuff is way scarier than actually seeing stuff. Not only that, but studies have shown that sound information travels faster than what we perceive through sight.
In terms of fear, sound causes a particular reaction in the brain, one that’s incredibly different than when the brain simply views something frightening.
Whether audio recordings are unexplained frequencies, spooky voices of serial killers, nature’s fury, exorcisms, signals and sounds or emergency calls made to 911 operators, the fact of the matter is, they always find a way to haunt us in our sleep when we least expect it.
The above frightening audio recordings are just downright unnerving and might make you feel really uneasy.
