The Windsor Hum
📅 2011 – 2020 · 📍 Windsor, Ontario, Canada
For years a rumbling low-frequency hum rattled windows in Windsor, Ontario. Investigators traced it across the river to an industrial island in Michigan.
What happened
From around 2011, residents of west Windsor, Ontario, reported a deep rumbling hum that rattled windows and kept people awake. It came and went without warning and could be felt as much as heard.
Studies funded by the Canadian government, including work by the University of Windsor, pointed to Zug Island, a heavily industrial island on the Detroit River in River Rouge, Michigan, home to steel-making blast furnaces. Because the source was in another country, Canadian officials could not inspect it directly.
In January 2013 the Government of Canada announced funding for a study into the hum, and in February 2013 a monitoring station was set up to record it. A 2014 report on the findings pointed to Zug Island as the likely source.
Residents reported the hum largely disappeared after US Steel idled its operations on Zug Island in 2020.
Not confirmed: investigators never had access to Zug Island, so the source was never inspected directly. The Zug Island link rests on the direction of the sound and on the hum fading after the furnaces were idled, not on a measurement taken at the equipment.

🔍 The evidence
- Low-frequency sound and seismic monitoring around west Windsor.
- Thousands of residents’ reports logged by local officials.
🤨 The skeptic’s view
- Blast-furnace equipment on Zug Island is the most likely source, which fits the hum fading after operations stopped. This is not confirmed, because nobody outside the site could inspect the island.
- Skeptics note that not everyone hears a hum like this. Tinnitus (ringing or buzzing generated inside the ear) and individual sensitivity to low-frequency sound can make some people notice or be bothered by a faint noise that others barely register, so some reports may not trace back to one source.
