The author follows the intro to that topic (which says nothing about EM waves causing 'sound' I might add) by saying: Finally, there's a body of empirical evidence that makes this theory more appealing. A study funded by the Canadian government and led by University of Windsor mechanical engineering professor Dr. Colin Novak spent the last year listening to the "Windsor Hum" that's been torturing residents in the Windsor area of Ontario since 2011. If you read the intro to that paper, it's very clear that it was acoustical noise that was measured and likely to be caused by a blast furnace. So that study provides no evidence at all that EM waves are causing 'noise'. The author continues with: The study concluded that not only does the Windsor Hum actually exist, but its likely source was a blast furnace at the U.S. Steel plant on Zug Island, which reportedly generates a high volume of VLF waves during its hours of operation. The study did not find that the blast furnace was radiating VLF waves (VLF being a term limited to EM waves) but rather that it was emitting sound waves in the 30-35Hz range. 30-35Hz is the SLF EM range, so even if the author conflated the types of 'waves', I'm not sure where they got VLF from. And then: Dr. Novak's study caps off decades of Hum theories No, it really doesn't, it just found a loud blast furnace. Not to take anything away from the work needed, locating a sound source at frequencies that low in a complex environment isn't trivial.
