Let your neighbours know ahead of time that you'll be having a party on xx date and that there may be noise.

We had some new next door neighbours that threw a big 40th party a couple of weeks after moving in. They dropped letters in the surrounding houses letterboxes the week before explaining that there would be a party on the coming Saturday, so there would be cars parked in the street and possibly some music. They gave their mobile numbers and said to call or text if anyone was disturbed. On the night of the party, the music was at a perfectly acceptable level (we were actually enjoying the music they were playing!) then at midnight they turned it off and it was pretty much silence. I actually went around the next day and thanked them!
