👂 Stat of the Day: Hmmmm…

Residents of the Scottish Isle of Lewis in the Hebrides are slowly being driven mad by a persistent and mysterious low-frequency hum of unknown origin.

The constant 50 Hz hum, comparable to a car or truck engine idling several yards away, has been reported by ~200 people on Lewis and confirmed with spectrograph recordings taken across the entire island, local resident Lauren-Grace Kirtley told BBC.

• Kirtley said in a recent Facebook post that the hum is less noticeable on the island’s center and strongest on its east coast, indicating the source is likely offshore.

A familiar tune: The reports from Lewis join a host of other mysterious hums heard by groups of people around the world for decades. Hum-hearer Glen MacPherson, a former University of British Columbia lecturer, founded the World Hum Map and Database Project to document and map the phenomenon.
