Because I want to listen to my own music and watch episodes of The Lizzie Bennet Diaries and etc?

Too much exposure time causes headaches by causing your brain to try too hard to get enough glucose and oxygen to keep up, and causing a pressure headache. The headaches from too high a volume and too much 5G exposure both should dissipate very rapidly when the program is turned off, usually within 5 to 7 minutes on their own.
Too much volume can also cause nausea.
That's just the thing. There's definitely not too much volume, especially since they are not in my room where it is playing, ever, and even if they were, wouldn't I be the worst effected since I spend the MOST time there?
They are also claiming that their headaches aren't dissipating even with THREE HOURS of non-exposure. They seem to think they need at least THREE DAYS before their headaches would go away.
Played at an appropriate volume, what is the range of exposure anyways? They're hundreds of feet from the speakers the majority of the time and through several walls and/or floor and ceiling.
I'm pretty certain they aren't being exposed nearly as much as they say they are. They'd have you believe that as long as they are in the house at all, they're exposed.
So, I'm going to prove to them it's all in their head. I just had the brilliant idea that I'll tell them I've turned it off next week while I have the single-tone ultrasonic playing. I already started the pure silence track, and they aren't going to be told that the subliminal isn't running. In fact, if they ask, I'll tell them it is. As much as I hate lying, this is in the interest of science.
