January 31 – The Sound Some People Swear Exists

0:00 Speaker 1: Welcome back, dear listeners to the Strange History podcast, where

0:04 Speaker 1: history occasionally asks an uncomfortable question, what if you're hearing

0:08 Speaker 1: something and no one else's Today is January thirty first,

0:13 Speaker 1: and this date often appears in collections of winter folklore

0:16 Speaker 1: and modern mystery for one simple reason. It sits at

0:20 Speaker 1: the end of the coldest month, the quietest stretch of

0:23 Speaker 1: the year, when silence gets loud enough for people to

0:26 Speaker 1: notice what's been there all along. This is the strange

0:30 Speaker 1: true story of the hum, the sound that refuses to

0:33 Speaker 1: prove itself. Across the world, a small percentage of people

0:37 Speaker 1: report hearing a persistent, low frequency noise. It's described as

0:42 Speaker 1: a distant engine, a vibration, a rumble, felt more than heard.

0:48 Speaker 1: It's not tonightas it's not constant for everyone, then it

0:51 Speaker 1: doesn't show up on recordings, but to the people who

0:54 Speaker 1: hear it, it's unmistakable the hum with no source. Reports

0:59 Speaker 1: of the hum began appearing in Earnest in the mid

1:01 Speaker 1: twentieth century, but one of the most famous clusters occurred

1:05 Speaker 1: near Taos in the early nineteen nineties. Residents complained of

1:09 Speaker 1: a sound that was worse at night. It interfered with sleep,

1:13 Speaker 1: It caused headaches. Some said it followed them indoors. Investigations

1:18 Speaker 1: were launched, Engineers listened, microphones were deployed, Data was collected,

1:24 Speaker 1: Nothing definitive was found, and yet the reports continued. Why

1:29 Speaker 1: January makes this worse? Winter amplifies the hum at least perceptually.

1:36 Speaker 1: Cold air carries low frequency sound. Differently, nights are longer,

1:40 Speaker 1: background noise disappears, people spend more time in stillness, which

1:45 Speaker 1: means the line between external sound and internal perception gets blurry.

1:50 Speaker 1: Some scientists believe the hum may be a combination of

1:53 Speaker 1: environmental noise, infrastructure vibration, and heightened auditory sensitivity. Others think

2:00 Speaker 1: it's neurological, and some admit they simply don't know. The

2:04 Speaker 1: strangest part, not everyone hears it. In fact, most people don't,

2:09 Speaker 1: which makes it deeply unsettling for those who do. Imagine

2:14 Speaker 1: insisting a sound exists calmly, consistently and being told it

2:19 Speaker 1: absolutely does not. The hum isn't dangerous. It's worse than that.

2:24 Speaker 1: It's ambiguous.

2:26 Speaker 2: Why January thirty first fits.

2:29 Speaker 1: January thirty first doesn't mark the discovery of the hum.

2:33 Speaker 1: It marks the end of the quiet season, when people

2:35 Speaker 1: either stop noticing it or finally can't ignore it anymore.

2:40 Speaker 1: The hum lives in the space between silence and sound,

2:44 Speaker 1: science and experience, explanation and doubt, and history is full

2:50 Speaker 1: of things like that. Before we wrap up, a brief

2:53 Speaker 1: message from today's unofficial sponsor.
