For years now, a low, rumbling hum has plagued the residents of Windsor, Ontario – just across the river from Detroit.
Known as the "Windsor Hum," some say the mysterious noise is so intense that it's more easily felt than heard.
"It has been described as sounding like an idling locomotive, a transport truck and running refrigerator," the Canadian Broadcasting Corp. wrote in 2014. "People have complained about sleepless nights, rattling windows and headaches."
The sound has even been blamed for the death of a goldfish.
To make matters worse, experts say, the sound arrives without warning, at irregular intervals. It has baffled scientists, locals and politicians, who can't agree on the best way to investigate the matter.
Government studies in 2014 traced the sound to U.S. Steel Corp. operations on Zug Island, an industrial property in the city of River Rouge, Mich., which lies just south of Detroit, according to the National Post. Officials from the Canadian Department of Foreign Affairs and International Trade told the paper that they were unable to access the site -- because it lies on the other side of an international border -- and failed to pinpoint its source.
"It’s like chasing a ghost,†University of Windsor professor Colin Novak, who has investigated the sound, told the CBC.
