Where is the ‘Windsor hum’ coming from?

In the summer of 1966, I was 18 and had just finished secondary school. I was selected, with a group of other British schoolboys, to make an educational tour of eastern Canada. It lasted about month with a week-long sailing from Liverpool to Montreal and a return week-long sailing from Montreal to Southampton.

In Canada, we visited wonderful cities like Quebec, Montreal, Toronto, Ottawa, Niagara Falls and Sudbury plus some smaller towns like a place called Windsor in Ontario. Now this week, I learned that the poor citizens of Windsor have been plagued on and off for six years by a mysterious hum. It is believed that the cause of the noise is a US Steel plant on the island of Zug which is American territory.

But so far there is no certainly of the cause and no plan for a remedy.
