Honestly, I fantasize about violently destroying people's speakers in front of their face, and the satisfaction helps me sleep.

Interestingly, when the noise is on the weekend, it doesn't disturb me as much, because I don't get angry, because I feel like people have a right to party on the weekend. Likewise, I'm unbothered by crying babies, barking dogs, and construction. It's my anger at people being inconsiderate that keeps me awake.

I've also found that it helps to get into as deep a sleep as possible-- when I've done hard physical work, taken a hot bath, and/or eaten a lot of carbs before bed, I sleep through noise that others complain about the next morning. And no, that's not my snoring.
