How much land do I need (with a twist!)

Okay, so... I debated using an alt account for this, but it's not like I hide my condition or anything. I have severe hyperacusis. It comes with a real bad sensitivity to not only loud sounds but also certain frequencies.

Due to my condition, I currently can't live a normal life. I can't hang out for long periods in developed areas or even be inside my own house without the power off. I had to quit my job and everything.

Headphones don't work—the only way I've been able to find relief is by spending all my time outdoors. That's been more difficult since the cicadas became active, but I digress.

I've been looking into buying land out in the middle of nowhere and building a place I can live with my issues in mind. I'm even hoping with the right infrastructure in place, I can still keep things like air conditioning and internet.

The catch, and the reason why I'm asking on here specifically, is that I have a few conflicting requirements that I just don't know enough about to reconcile:

1. I need enough land to minimize sounds from neighbors. Ideally, enough to not be able to hear them at all, given the frequency range that affects me most involves sounds that are barely audible and can travel quite far.

2. This also means no heavy machinery. I can't personally operate or be near a tractor/ATV, inverter, ultrasonic pesticides, etc. Many things that would make it easier to manage a large amount of land are beyond me.

3. I'm poor as fuck, so whatever I do, I need to take out a loan to do it. As a result, the place needs to be able to turn a reasonable profit without relying on machinery.

Any advice or suggestions on how much land I'd need, where best to buy it, and just generally how to make this work would be greatly appreciated! Thanks in advance.
