OK so, serious answer, Kong mentioned this in the chat. If you're used to sleeping in peace and quiet, you just need to accept the fact that it's not going to happen anymore. Solution: white noise.

My entire family has slept with fans on since as far back as I can remember, now I can barely sleep unless there's one on around me to drown out noise. So pick something, fan, computer noise, AC unit, one of those white-noise generators, pick something and use that. It may not eliminate all outside noise, but it'll go a long way to drown it out.
