I did, but I may be wrong. Wikipedia says tea trees are used.

What if I can hear wi fi? How could I tell?

Wouldn’t it be bothering you if you could?

Well, I suppose not necessarily… I hear a hum but it does not bother me because I don’t generally fixate on it. When I notice it, I then realise I’m being lazy and need to get out of bed and get my attention on something. Some people suffer, like Diane Schou, who moved to a town that didn’t trigger her electromagnetic hypersensitivity.

I suppose a test would be to enter a sound-proof room which then also has a faraday cage, and get tested. The tester would have controls for emitting sounds mostly outside the statistical hearing range, along with one to turn on a wifi AP, and some dummy switches that emit nothing. Then for you to raise your hand when you hear something. I read about someone taking a test like that, and she raised her hand whenever some electronmagnetic something was played (wi-fi iirc). It was something that was unusual and surprised the researchers. I cannot find the story on that now. Might have appeared in Wired mag… not sure.

Indeed. We also have to consider that it has become popular¹ to boycott the US over Trump’s tariffs and US support for Israel. These boycotts would discourage the use of US tech giants, in principle.
