Since the 1970s, thousands of people across the globe have reported hearing a strange humming sound incessantly pulsating in their ears – and we’re not talking about tinnitus.

The strange hum has turned into such a compelling mystery that there’s an entire website dedicated to studying and documenting the phenomenon. There you’ll find an expansive map where recreational researchers have crowdsourced hundreds of locations where they’ve experienced the hum.

In a new short documentary for BBC, journalist Linda Geddes goes on a thrilling quest to pinpoint the source of the strange hum.
Oh, and don’t forget to let us know: Have you been hearing the hum?
