The Hum

ParaReality

Can you hear the "Global Hum"? Tens of thousands all over the planet claim they can hear a strange, perpetual background "hum" (sometimes referred to as the "Worldwide Hum"). Many describe it as an ongoing, low-frequency sound like that of a big truck idling a mile away, 24/7.
Some areas, like Taos, New Mexico, have been famous for such a hum for decades.
What is the mysterious global hum, and is it just noise pollution?
The Hum is experienced as a consistent, low-pitched noise, much like the sound of a large truck idling in a nearby parking lot. Those who hear it tend to report experiencing it in urban areas – leading some to conclude that it is, in fact, a form of noise pollution screened from most people by the general city soundscape.
