A strange phenomenon has been affecting a small group of people throughout the world. It’s a localized, persistent low frequency hum that has been a nuisance to residents everywhere from North America, Europe and Oceania.
Not everybody can hear it, but the “hearers” remarkably describe the hum in the same way. It appears to resonate at the 56 Hz frequency range. It doesn’t have a natural sound and by most accounts, the hum is reminiscent of a diesel engine running in the distance. The hearers claim that the sound intensifies if you’re indoors and the vibrations can be felt through the skin. To make matters worse, the continuous hum has caused the hearers to suffer from loss of sleep, dizziness, anxiety, irritability and in one circumstance, suicide.
