Noise from neighbors is the biggest thing that drove me to move to a single-family home.
A company I worked for had to abide by it, we'd be on-site at the customer address and start work promptly at 8.
Obviously that's why not that many people live in a yachting community, and those that do, hate it there ;)
Compared to suburbia where neighbours started mowing at 7am, loud parties went late into the night and dogs barked all day, it's oddly quiet.
