I hate all unnatural noise.
Sounds I hate: people talking, dartboards, people walking around upstairs, cars, groups of people, crowds, sporting events, etc...
Sounds I like: rain, wind, animals. That's it.
Music is good, too, but that's highly dependent on my mood. Right now I'm working on a few projects, one of which requires a ton of concentration. I want to sit around and just think. I can't think with music, and I can't think with a crowd outside my door playing darts.
I put on headphones, but that only adds to the noise. I can still hear the darts and loud voices over the music.
*sigh* 9.5 more months of living here. After that, my Montana plan is sounding better and better. I just want to be alone, undisturbed.
