Dude?

The classic description of the Hum is that it sounds like a truck engine idling. For some, it’s a distant rumbling or droning noise. It can start and stop suddenly or wax and wane over time. For others, the Hum is loud, relentless and life-altering.

I eventually came across one of the few serious papers on the topic. It was written in 2004 by geoscientist David Deming (who’s also a Hum hearer).

Deming began by describing the standard history: The Hum was first documented in the late 1960s, around Bristol, England. It first appeared in the United States in the late 1980s, in Taos, New Mexico.

He then examined the competing hypotheses for the source of the Hum. Many have pointed to the electric grid or cellphone towers. But this theory is dismissed on two grounds: cellphones didn’t exist in the 1960s, and the frequency emitted by both cell towers and the electric grid can be easily blocked by metal enclosures.
