I don't know why all the fuss. I'm planning on mining (1-2 Antminer S9's) in my house. The house isn't huge and I know it will be noisy but meh, it is what it is. Most people say that without any kind of soundproofing or noise reduction, the miners run between 70-80dec. What you can do to try to understand that level and pitch of noise is run a very loud vacuum cleaner and a microwave simultaneously. This gave us about the right decibel with the higher pitch of the vacuum thrown in. When we did that, you could barely hear anything upstairs, and that's without noise reduction measures. But our house layout and setup could be very different than other people. To give people an idea of how I have things at home...
1.) House is about 2,000sq ft.
2.) House is 2 story. Miner will be downstairs, we stay upstairs about 90% of the time
3.) There is an entry/shoe room (where the miner/s will be) that has a door separating it from the rest of the house.
4.) Purchasing soundproofing foam to put in that room on the walls and ceiling. Like this (

5.) Also will be doing the cooler setup, especially if running more than 1 miner. See more about that here (

Not sure what else to say really, I have everything figured out except for HOW TO GET A MINER!

Seems I can't ever get my hands on one. We'll see how long it takes. Although, it may be a good thing to see how everything looks at the beginning of the year before I get my hands too deep into it!
If anyone is interested in my situation and how I have calculated things for "estimated" earnings, etc, let me know and I'd be happy to share. That said, I don't pay electricity costs (other than getting upgraded fuses for the house if I run 2 miners) so that is 1 cost I don't have to worry about.
