Years before diplomats in Cuba were assailed by grating noises and left with baffling brain injuries, the residents of a Canadian city began hearing maddening hums and rumbles. The deep noises mysteriously wash in and out of their neighborhoods and homes, hitting the ears of some but not all residents. And according to recent local news coverage, the eerie disturbances are now getting bad again.
Since 2011, some residents of Windsor, Ontario—directly across the border/river from Detroit, Michigan—reported intermittent bursts of noise established as the “Windsor Hum.” It’s described as a low-frequency throbbing sound, like a fleet of idling diesel engines, a distant rumble of thunder, or a roaring furnace. Some “hummers” report feeling vibrations, too, and having items in their homes rattle. They’ve linked the hum to depression, nausea, sleep problems, heart palpitations, ear aches, headaches—not to mention widespread annoyance.
Windsor residents are not imagining it; there is a real hum. A months-long investigation by National Resources Canada in the summer of 2011 identified a prominent, air-borne frequency of approximately 35Hz. There have been plenty of recordings and reports since then. And its existence was confirmed in a 2014 investigation carried out by the University of Western Ontario (UWO) and the University of Windsor, which was supported by the Canadian Department of Foreign Affairs and International Trade (DFAIT).
