My neighbors around the corner put in an inground pool this past fall. We do not know these neighbors. Their backyard corner touches our backyard corner, but the lots are pretty deep and there are trees, so we can't see their yard. A stockade fence was put in as part of the pool project.

The issue is the pool equipment. At least that's what I think it is. We hear a humming noise, especially from our bedroom which is closest to their yard. It's all the time, but especially noticeable at night when all else is quiet. We live a mile from a state highway and a freight rail, which isn't bad, but this is waking up DH at night and keeping him up. This is not a good thing. Me, I have tinnitus so it's one more annoying layer of noise for me, but now that I know it's the pool equipment I'm getting really annoyed. I walked out to the corner of the yard tonight and also walked around the block, and I was able to locate the loudest sound as being in the backyard of that house.

My question is, what can I ask them to do about it? Another pool across the street on a corner is quiet, and I walk by it all the time and rarely hear equipment sound. Is there something going on with this new pool because it's new and it's winter? I don't want to go over and right after introducing myself ask them to turn off something they can't turn off, even for 7 hours at night.
