I am stressed by my neighbor's car noise. He has several cars, one is so loud (and a low frequency) it rattles our pictures on the wall. Our houses are very close to one another on a small private road. He turns it on randomly, revving it, any hour of the day or night. This has been going on for years. It's woken me up. It's interrupted our "wind down" time before bed. It drives me crazy because it penetrates my ear cavity, a low, spontaneous vibration in my brain, and I have no control-- we've tried talking with him, arguing with him, calling police, putting up a fence, discussing with other neighbors, etc, to no avail. He is also a bit aggressive, enough to frighten one of the neighbors, and I bought security cameras to give me and my family a little piece of mind. We live in a state where household guns are quite common (we do not own any), so that adds to my worry, whether it is an actual threat or not.<p>All I can do is hope that we move soon, but the housing market is not helping. I also try to focus on the moments of calm when I cannot hear his car. It takes considerable mental effort not to acknowledge the noise and let is alter my mental state.<p>For example, I work mostly from home, so I went outside yesterday to relax in the sun, only if for a few minutes, and he started up his car, shattering the air and any relaxation. I went back inside my house.<p>For me, hope, is the key. I can only hope that things will get better, and to be patient that they will. I tell myself that this only temporary, and will someday become a memory in the past. Another way I cope is to take many small vacations. It's amazing when we stay somewhere and don't have to worry about loud, spontaneous noises. Noise pollution is a thing!
