SYSK Selects: How The Hum Works

# Stuff You Should Know - The Hum

Josh and Chuck dive into one of the internet's most perplexing mysteries: the Hum, a mysterious low-frequency rumbling sound that about 2 percent of people worldwide claim to hear, despite nobody else noticing it. The guys explore where this phenomenon pops up (mostly in Western countries), who experiences it (typically folks over 50), and the wild range of explanations—from industrial machinery and secret military transmissions to mass delusion and electromagnetic waves. They also examine some genuinely unsettling cases where people have attributed violent acts to the sound, making it clear that for sufferers, this isn't just annoying background noise—it's literally life-ruining, and nobody has any solid answers.
