These were my neighbors growing up. Chain saws, quads, backhoes, bulldozers, fire engines, school busses -- anything with wheels and big motors they would be running all day long. Every day during the summer I'd wake up at 8am to 3-4 quads being driven around outside my window by the neighbor kids, and that would go on all day long until sunset. That actually wasn't bad though compared to moving to San Francisco, where they decided to carve a narrow chunk out of the side of a solid-rock hill right below my window. Jackhammering all day from 7am until 5pm. I bought a sound meter and complained several times that they had exceeded the sound limits but no one cared. It really affected my wife, we had just moved to SF and she had no where to go while I was at work. She tried libraries and parks and such but there were too many homeless there and they harassed her. She has trouble sleeping due to mental health issues and she usually sleeps from 4am to 12pm, but she couldn't do this due to the jackhammering outside of our window that started at the crack of dawn. This meant she didn't sleep at all for months, and she ended up having a psychotic break, for which she was hospitalized. She was sent to a hospital in Santa Clara, and I drove there every day to see her. Anyway, all of this is to say that noise issues are serious to some people, and there's really no limit to how much noise someone can make. You can complain but nothing happens.
