I've heard of AM radio being audible in non-electric structures, like an old hangar door. Some combination of geometry, metal surface condition (corrosion?), and proximity to a station.

Well, if you're mad enough and don't care about trivial things like life, you can listen to AM radio by just touching the mast with any random item:

Why am I not surprised to hear the odd «сука» in that video?

There's an anecdote of someone hearing voices, but it turned out to be AM radio.

They found out it was the metal in two cavity filling that made the teeth vibrate and transmitted sound to their ear.

Not sure if it's just an urban legend or legit, but I like that story.

Lucille Ball very famously told a story on the Dick Cavett show about hearing radio transmissions in her tooth fillings in 1942 and it leading to the capture of a Japanese spy station. [0].

While the story seems a bit far fetched, having fillings act as diode rectification of an AM signal that is then conducted into sound via the jaw is completely real and has happened to many people, particularly moreso in the past when people more often had metal fillings and very powerful AM signals were more prominent.

All you need is a rectifying junction: https://en.m.wikipedia.org/wiki/Foxhole_radio

Primitive diodes.

Poorly shielded wires and speakers can pick up stations as well. My brother's cheap guitar amp would randomly pick up garbled bits of sound from radio stations (while not plugged into any power source)

>Poorly shielded wires

That's literally an antenna[1][2], actually.

SoundBlaster / Cambridge SoundWorks set of subwoofer and satellite speakers with long wires did this, too. Freaked me out when I suddenly heard voices inside my apartment at night. Turned out it had suddenly started to pick up a radio talk program.
