Is that your bed next to an SP20 & a S5? Do you sleep with industrial ear muffs strapped to your head?

That is dedication. Definitely could keep a eye on it that way though. I personally keep them out of bedrooms

You stop being able to hear it after a while, its surprising what level of noise can become the baseline. Its also a lot easier because miner noise is perfectly level.
I own a very small house. Only 400 square feet total.
So, I have no choice but to keep mining equipment within my living space. Also, I am an on and off smoker and like a clean smelling house, so I run a HEPA air purifier on turbo speed 24/7.
I sleep like a baby with 2 SP20s and 2 S5s running at full tilt about 3 feet away from me.
If I turn off every fan in the house, it is uncomfortably quiet.
