One of our earliest episodes was about a mysterious hum that was haunting residents of Windsor,

Ontario and Detroit, Michigan.

When we first launched the episode back in early 2017, it got a big response, and over the

years, people would bring it up all the time.

For a long while, though, there seemed to be

no resolution to this story. Then recently, seemingly out of nowhere, I got a wave of emails

and tweets that brought this story back to my attention in a big way. So what you're about to hear

is a totally updated, remixed, and revoiced version of our fourth episode,

but this time with an actual resolution.

You're listening to 20,000 Hertz.

There's a place right on the border between Detroit, Michigan and Windsor, Ontario, where

there's this hum.

It's so low that it takes a long time to even notice it, and you can't hear it everywhere.

But in some places, especially on the Canadian side, the noise can get so loud that it rattles dishes.

No one knows for sure what the sound is, or what's making it, but it keeps people up at night.

The sound even has a Facebook group with over 2,000 members who discuss it and speculate what might be causing it.

It's known as the Windsor Hum.

This is an actual recording of the Hum, but we've applied some processing to make it more audible.

Imagine if this sound was happening around you all the time, when you woke up in the morning,

while watching TV, when you went to bed at night.

Do you think you could eventually tune it out? Or would it drive you mad?

Honestly, I don't think I could handle it. It turns out, this isn't the only place
