Two unrelated anecdotes: 1. A few years ago I spent some time in Falmouth, MA and there was an ongoing battle over newly installed wind turbines. The humming sound was getting to people, including to the point where they were getting headaches. Some people heard it and others didn't. The locals were going to war with the initiative. This article reminded me of that and I checked in on the ordeal. Looks like they shut…

I'm just glad they identified the source of the hum, many people are impacted for years by unexplainable sounds, and it is maddening. It took me and my neighbours a month to find the source of a hum that was resonating with our windows. It was torture, with midnight walks and lurking around potential sources, mapping nearby industrial sites, and questioning our sanity, while our windows were vibrating without a stop.…

I think the complaints about Falmouth wind turbine noise are eerily similar to complaints that wifi gives people headaches. I don’t think they are founded in reality.

This is very similar to an Aeolian Harp, also known as a wind harp. https://en.wikipedia.org/wiki/Aeolian_harp https://www.youtube.com/watch?v=CtzSm76ppS4 They are pretty cool art installations. The Golden Gate bridge may now be the largest such installation ever built!
